When reviewing a card in a filtered deck right before the clock hits whatever time you set as “next day”, you get an FSRS scheduling error and have to go back to the deck overview to continue using Anki. Don’t know if this also happens on normal decks.
Which app, which version, etc? Please provide the debug info.
Does it look like this?
I was studying just before 12:00 AM then I went to google some stuff and when I returned at 12:04 AM the study screen was still not updated (my new day start time is 12:00 AM). Attempting to answer threw a “card was modified” error:
Leaving the study screen fixed it.
AnkiDroid v2.23.3.

Yeah that’s it exactly; do you still need the stuff you requested?
Yes, it’ll be helpful. This bug was supposed to be fixed in 2.24.
You can find the debug info by going to settings → about → copy debug info.
Also, to confirm, you were using the new study screen when this bug happened right?
