I’m on CMF Phone 2 Pro, nothing particularly old. Often I get “Bunpro has stopped working” which prompts the app to get closed. If I don’t close it it pops up again until I restart the app.
I have a gut feeling it’s something to do with how many items I am learning or have learned (4k+ in reviews, 13k+ total) since it tends to happen after looking at the word lists.
It’s a tolerable inconvenience, but would be nice to see fixed.
