Game unresponsive if screen tapped to fast on card mastery [Investigating]

Upon winning a game, if you are tapping screen repeatedly to go through rewards and you happen to master a card the mastery dialog screen quickly disappears and all bottom buttons are unusable (Continue, Heal, Vault). The Battle Log button still functions though. Only way to fix is to close the app and restart which may make your win not count.

Happened to me a bunch of times without even mastering a card. When you tap fast to go through rewards, just do it on the “continue” button, it will exit the match normally right after the ribbons and avoid the freeze. (Never had the problem since i started to tap exclusively on this button).
