[2020] Minor issue on mobile post patch. Once you select the quest tab, you can’t click anywhere on the screen to close it. You must click either the top tab button or the bottom quest button. It’s not intuitive and the UI for others selections like weekly vault work like you would expect on mobile.

Hello, this is not a bug but a design choice for the quest menu we wanted to try. We moved it to the side so you can be able to look at it in deckbuilder, rewards or other screens.
The thinking is you could open the menu, see you have a Fearsome quest for the day for example, navigate to deckbuilder without having to close and reopen the menu, and put together whatever you need to complete your quests.

We'll be seeing how people feel about it during the next couple patches. Thanks!

Hello, you can close it from any screen using the "Scroll" icon in the top right (the same icon you see on the home screen button. You don't have to navigate to home to do it.

Thanks for all the feedback, we can tell this button is not clear to players as it is right now.
