I have had this epub reader for a long time and it was one of the best. Even bought pro because I love it. However, recently when I try to open books in the app it says file not found despite having the file. I tried everything I can think of and the only thing that worked was deleting the book from the app (not the device) then opening the book from my files and it worked. Nothing else does and when I try to scan for new books it doesn't find them either. I hope this issue gets fixed soon...

my favorite EPUB reader (for android) I've tried so far but the bug where it highlights entire pages when trying to select text that's at the bottom or top of a page is infuriating and makes it impossible to highlight certain sections. I also wish there was an option for the contents list to include page numbers so you know when each chapter starts without having to check manually.

Great app for the most part. My only complaint is that accurately highlighting a passage can be quite frustrating, as entire pages will often get included when trying to capture the beginning or end of pages. The best, albeit imperfect workaround seems to be changing the font size, but this obviously isn't ideal. If this were to get fixed, the app would be an easy five stars.
