Hello there!
There have been a couple reported issues with this release that are affecting some players.
There is an issue with resetting daily/weekly quests that Wizards has discussed here: https://forums.mtgarena.com/forums/threads/60220/comments/359964
There appears to be either a visual or distribution bug for the renewal awards.
There appears to be some issues with the Mastery system:

Update - We have temporarily disabled the Eldraine Mastery system to address issues with Quest and Weekly Win resets. As a result, players will also be unable to earn Weekly Win and Quest rewards at this time.
The Mastery system should be re-enabled at approximately 10:30 a.m. PT. We'll update you with more information once it becomes available.
There appears to be some related store issues for some users in some regions; this has happened before with high-volume purchases on release day. No further information has yet been published.
The game remains in maintenance: https://magicthegatheringarena.statuspage.io/
Please discuss these happenings here.
Final Update:
External link →Verifying - We have resolved the issue with Quests, Weekly Wins, and Renewal Rewards. All players should have three Quests (including Quests in-progress prior to this update) and 0/15 Weekly Wins. Affected players should restart their game client at this time.
We are continuing to monitor the situation to ensure there are not further issues. Thank you for your patience!
