I am using Anki Desktop Version 2.1.49 and regularly downgrading (via downgrade&quit) to Anki Version 2.1.43 because of an Addon that doesn’t work on 2.1.49. So whenever I create Notes, I use the downgraded version and whenever I review my cards, I use 2.1.49 with v3 scheduler.
I am using Anki on iOS version 2.0.83, V3 enabled.
Somehow my card counts have started to differ on both my Macs and on my iPhone. I rebuilt database, restarted Anki, disabled all Addons etc., but card counts still differ. And obviously I synced via standard sync.
And I am not saying, the numbers on the deck screen differ from the number shown at the bottom when hitting “study now”. I am saying that the numbers on the deck screen differ depending on which device I use. I usually use one specific Mac, so I was shocked when I once saw the higher card count on my iPhone and even more confused when I looked at the other Mac.
On the screenshots you will see one specific deck with two subdecks. But the problem occurs for more or less all of my decks.
