I created a new deck (25k items, ~20MB disk space), synced it to ankiweb, then deleted it. After deleting the usage didn’t go down. I re-created the deck, uploaded it again, deleted again and the usage went even higher.
Now syncing my phone with empty ankiweb I’m getting a message that I’m downloading 80MB of data (unexpected) but no decks show on the phone (expected).
Is this a bug or is there some hidden feature / trash that I need to empty?
