If a NozomuNoto product does not work on your device, it usually comes down to one of four things: the wrong file was opened, the ZIP was not extracted, the app is in the wrong mode, or the app/device does not support the feature you are trying to use.

This guide helps you check the problem kindly and quickly before starting over. Use a fresh copy of the file whenever possible so troubleshooting does not damage the planner or notebook you already wrote in.

Quick answer

• PDF planner or notebook: open in a PDF note-taking app that supports writing and PDF links.
• PNG stickers or widgets: insert as images or stickers. They are not planner files.
• ZIP folder: extract first, then use the files inside.
• App-specific GoodNotes file: use it in GoodNotes. For other apps, choose the PDF version when included.
• E-reader device: expect simpler PDF reading and writing. Stickers, page copying, and app-style tools may be limited.

First checks

1. Check the file name and file type. Make sure you are opening the final PDF planner/notebook, not an instruction PDF, ZIP folder, PNG sticker, cover image, or preview.
2. Save the file before importing. Download to Files, Downloads, My Files, Google Drive, Dropbox, OneDrive, or another real folder first.
3. Extract ZIP files. If the product came as a ZIP, open/extract the ZIP and choose the PDF, PNG, app-specific GoodNotes file, or other file inside.
4. Open a fresh original copy. Test a clean file before testing a planner that has already been exported, flattened, merged, edited, or heavily decorated.
5. Test one basic link. Open the Index or a clear month tab and tap one link in read/view/hand/navigation mode.
6. Check the app features. The app should support the feature you need: PDF import, handwriting, PDF links, page thumbnails, page duplication, image/sticker insertion, backup, or export.

Check by symptom

1. The file will not open

What happens: the app says the file is unsupported, blank, damaged, or cannot be imported.

Common causes: the file is still inside a ZIP, the download is incomplete, the app does not support that file type, or the wrong file was chosen.

What to do: check the file size, download again if needed, extract the ZIP, and test the PDF in Files, Adobe Reader, Xodo, or another basic PDF viewer. If it opens there, the file is probably valid and the issue is the app workflow.

2. The planner opens, but links do not work

What happens: tapping tabs, Index items, dates, or buttons writes marks, selects objects, or does nothing.

Common causes: the app is in pen, text, lasso, image, or edit mode instead of link/navigation mode.

What to do: switch to read, view, hand, gesture, or navigation mode. Test one month tab, one Index item, and one page link. If all links fail in one app but work in another PDF viewer, use the app guide for link mode.

3. You can see the planner, but cannot write

What happens: the PDF opens like a document, but handwriting, typing, or annotation tools are missing.

Common causes: the app is a basic viewer, the file is opened in preview mode, or the device/app does not support PDF annotation.

What to do: import the PDF into a note-taking or PDF annotation app instead of only previewing it. On e-readers, check the device's PDF writing tools because they are different from tablet apps.

4. Page copying, template pages, or covers do not work

What happens: the planner opens, but you cannot duplicate template pages, move pages, change the cover, or manage sections.

Common causes: the app has limited page management, the tool is hidden inside thumbnails/page manager, or the PDF was imported in a way that disables page tools.

What to do: open the app's page thumbnails, page sorter, page manager, or page overview. If your app cannot manage pages, choose a different app for planner-heavy workflows or use the planner without custom page copying.

5. Stickers or images do not work

What happens: PNG stickers will not import, look blurry, show a white box, or cannot be moved after placing.

Common causes: the ZIP was not extracted, a preview image was used, the app does not support image insertion well, or the sticker was enlarged too much.

What to do: extract the files, insert one original PNG as a test, resize gently, and check whether the app can select/move the sticker later.

6. The planner is slow, crashing, or too heavy

What happens: the app freezes, pages load slowly, writing lags, or export fails.

Common causes: the planner is large, the device has limited storage/RAM, cloud sync is still running, or the app is handling too many images, copied pages, and stickers.

What to do: close other apps, free storage, use one planner copy, avoid adding many large images at once, and test a lighter app or device if needed.

7. The product behaves differently on an e-reader

What happens: the PDF opens on Boox, Supernote, Kindle Scribe, reMarkable, Bigme, or another e-reader, but the workflow feels different from iPad or Android tablet tutorials.

Common causes: e-readers are better for focused reading/writing and usually have fewer app-style tools for stickers, page duplication, drag-and-drop images, and fast navigation.

What to do: use e-readers for simpler PDF planning, handwriting, reading, and light annotation. Use a tablet note-taking app if stickers, page copying, and rich customization are important.

What to send if it still does not work

Send the product name, exact file name, purchase platform, device model, operating system if you know it, app name, app version, and the exact step where it stops. A short screen recording is often more helpful than a single screenshot because it shows what you tapped and what happened next. Please hide email, payment, and order details that do not need to be visible.
