What happens when you cancel your membership?

I recently had the Ankihub membership for 1 month and canceled it. However, when I tried to re-open my Anki deck, I got some message that since my membership is canceled all the Ankihub notes will be removed.

Does this mean my Anking deck reverted back to v11? Do I still have the latest Anking version, just without additional Ankihub notes?

Can you screenshot the message you’re seeing? AnkiHub won’t revert you back to anything. I’m not sure what you’re referring to
