I’ve been having an issue with 2.1.45 … my cards are flagging and suspending as expected, but none of the colors are showing up in the browser itself.
I’ve tried all the steps from the Anki manual (restarted computer, opened Anki without add-ons, restarted Anki, and checked the database). I have two Macs, both experiencing the same error (one running Big Sur and the other … whatever came before Big Sur).
It wasn’t fixed when I upgraded to 2.1.46 (± add-ons), but did get fixed when I downgraded to 2.1.44 (even with all add-ons enabled).
