Searching accessible audiobook reading app to replace Voice Dream Reader and BookPlayer

Hello, for a long time I have been using Voice Dream Reader iOS app for reading both audio and text books. However, since I started to encounter issues with some books in my library getting corrupted and unavailable to play and random skipping of audio tracks during playback, I replaced Voice Dream Reader with BookPlayer. But now with BookPlayer, I am once again facing troubles of not being able to import any audio book. Whenever I open the import screen and press the Done button, no book gets imported. Therefore, I am again searching for an accessible replacement audiobook reading app for iOS. Please do you have any recommendations?
