Quick answer
Use bookmarks when it is the shortest path to the place you want.
Bookmarks save chosen places that you want to revisit.
Do not use it when
Another tool already matches what you know better. Too many bookmarks lose their meaning.
Example
If you remember the word “photosynthesis,” search is faster than contents. If you remember “Chapter 6,” contents is faster than search.
Simple rule
Use words for search, structure for contents, chosen places for bookmarks, last place for progress, and recent books for history.
Detailed troubleshooting checklist
Work through the problem in this order: first check bookmarks itself, then the app, then Android or the device. Keeping that order prevents you from changing many things when only one part is wrong.
- Change one setting at a time.
What to remember
The answer does not need to be complicated. The useful result is that you can choose the fastest navigation method for the task without repeating the same setup every time.
Practical reminder
Use the smallest fix that gives a clear result with bookmarks. Then close the app or put the material away and repeat the same task later. If it still works without extra setup, you have a reliable solution.
