Quick answer
To keep study notes offline, store the book or document locally, open it once, download any needed voices or dictionaries, and test everything in airplane mode.
Prepare before you leave the connection.
Download the real file
A cloud preview is not always a local copy. Save the file to the phone or mark it available offline.
Test the main task
In airplane mode, open the file, move to another page, search, and try read-aloud if you plan to use it.
Know what still needs the internet
Cloud sync, online lookup, and new downloads can fail offline even when the book itself works.
Keep a backup
Travel can be a bad time to discover a file is damaged. Keep another copy somewhere safe if the document matters.
If the first fix does not work
Try another known-good study notes example. If the second one works, the first file or item is probably the problem. If both fail in the same way, the app, phone, or setting is more likely.
