The following issues are in the game as of the Apr 26 update:
– Some suspended matches (Best of 3, Best of 5, Take Two: Create your own deck, and Take Two: Create opponent’s deck matches) can't be resumed.
– Phoenix Roost causes matches to be cancelled when played. While we work to implement a fix, this card will not be available on the Decks screen. It will also be temporarily unusable in ranked, unranked, Take Two, regular private, Take Two private, main story, or practice matches.
We are currently investigating and working to fix these issues. We apologize for the inconvenience caused and thank you for your understanding.
