Progressing through cards struggles / fails when on spaced repetition mode
I noticed this when my phone was on low power mode at 5%, it may be relevant. I noticed that in spaced repetition mode, when I tapped and then tapped again, the next card would not appear. Tapping on "remembered" did nothing. Tapping on forgot would progress the cards after the delay, but only after another tap would the flash card show up correctly, half of the previous flash card was still there.
Plugging my phone in did not immediately fix the issue, but clearing out all the past reviews did. This will make it hard to repro. Perhaps the library struggles to add a review when there are already many / recalculating the schedule is costly. Even then though it seems to freeze up entirely.
