I have been using the snooze power-up, which works great on the web version of Trello. When the snooze period ends, the card always reappears on the web version of my boards with no problem.
Unfortunately, on several occasions I have noticed the cards don't always reappear in the Android app--sometimes they do and sometimes they don't. I can't figure out any pattern to the ones that reappear in the app vs. the ones that don't.
I have tried fully exiting out of the app and reopening it, but that has not fixed it. Has anyone else experienced this? Any ideas?
