I started playing last week for the first time ever, it was not initially doing this and quests were functioning normally. Now:

My daily quest does not reset ever and has a 24H timer which, upon reaching 0 each day, goes straight back to 24H waiting. There is therefore never any quest for me to complete.

It has been doing this for around 4 days now, and I am missing out on a lot of mastery progress. There was no obvious cause for this starting to happen except playing the game normally. I am a new player getting into Magic for the first time with the Final Fantasy collab and this is very offputting.

I have rebuilt the game files, logged out and in multiple times and uninstalled and reinstalled the game. Nothing seems to be working.

Suggestion-
Having played other games with season pass models and seeing how many people are experiencing this issue, the obvious appropriate action seems compensation in the mailbox for progress lost in (inc. paid) mastery for those unfortunate enough to experience the issue. Neglecting to fix an issue like this that blatantly affects paid features so directly seems incredibly amateurish coming from others games, let alone not addressing it at all.
