We've been investigating this. Looks like this is a visual-only issue that kicks in once you have all of your quests complete. Though you can't see it, you will still be getting progress for daily & weekly wins, etc. We're actively working on a fix for this.
Any info on this guy's post - https://www.reddit.com/r/MagicArena/comments/mrkvst/lost_connection_to_server_after_drafting_i_did_a/
I haven't been able to play at all today after completing a draft and it looks like a lot of other people are having the same issues.
We're actively looking into this. We understand what caused it, and are currently investigating solutions. Unfortunately I don't have any more info than that. We understand that this is very frustrating, and I apologize for the bug. We're working hard to resolve it.
Not sure if this issue has been brought to your attention, but all five of the super rad quiz card sleeves for Strixhaven show up as the basic Magic card back.
We're aware and are working on a fix; thanks for the report.
