Can't return to my deck from deck detail page in Sealed deck building
I'm currently playing an Avatar BO1 Sealed on my Samsung Galaxy S20 5G FE and the following issue came up:
During deck building I switched to the deck detail page to see how many creature and spells I had in the deck and how the colors were distributed. From there I couldn't return to the deck building page. Whenever I tap the return button it opens the deck name changing window.
