I haven’t been able to reproduce this consistently.
Problem:
When reviewing a large stack of practice flashcards, (50+) occasionally the “continue” button will glitch, and not allow me to press it.
Things that resolve it:
just waiting (5+ seconds) seemed to work the second press Most of the time. If it did not I would then try exiting the app (but not force closing) and when I came back I could continue.
Context:
I imagine this is mostly just because I was going through quite quickly, just trying to figure out should I review more slowly or practice in shorter batches. Will update if I run into again, but I’m out of cards to practice till I add more!
