This took me down a rabbithole of testing. I was originally happy to hear your reply and thought that maybe the problem was just my phone. Sadly that doesn’t appear to be the case, and the problem appears to plague any RAB or SAB app I build. I’m interested in testing builds from other people, particularly in RTL languages. Did you say that you built the app? If so, could you send me the arm64 version you created?
If your version works, then I might ask you to send me your sdk folder so that I can test using it. I had a horrible time getting the Android sdk to work correctly, so I’m not 100% confident my build is good.
It’s not that RTL swiping sometimes works–it never does. LTR moves to the next chapter, but RTL swiping doesn’t move to the previous one.
