If during a review I tap “Edit” to edit the Note, make a change then save, when I resume reviewing it no longer records my answers. The card changes after every answer, but the stats don’t update. And if I log out and log back in, I am shown the same cards again, and stats still don’t update. It seems at some point it starts working again tho, because if I try again the next day it works normally again.
This seems to me to be a bug. After editing a note it’s no longer possible to continue reviewing.
