Ratings and reviews

Edit: Uninstall and reinstall the app. It prompts you to allow storage access again. Old: This app is great almost 100% of the time, however, for some ebooks that have long chapters, the app will sometimes start to slow down whenever its doing an animation (scrolling, page turning, tap to bring up menu, etc.). This also doesn't always happen and isn't consistent, with a given chapter being super slow one day and fine the next.

It's great, just wish there was a way to reorder the categories, and add a book to more than one category at once Edit: recently when transferring books between devices, it won't sync my annotations. Very frustrating as I annotate everything I read Edit 2: for some reason it won't let me open any of my books, saying the file in unavailable. Can't figure out what's going on but may need to find a different app with all the issues coming up recently

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...
