How to report a bug
1. Give us the steps to reproduce the bug: play a Bo3 match and go to Sideboard after each game. When trying to Sideboard in the view where you can see cards better (top over bottom), can not remove cards from main deck. Repairing game files doesn't fix this issue.

1.   Note which platform you’re using (PC, Steam, Mac, Android, or iOS): Android
   

2.   Enter the actual results you’re experiencing:  can add cards to, but not remove from, the main deck. 
   

3.   Enter the expected results of the feature: The ability to properly Sideboard by adding ~and~ removing cards from the main deck
   

4.   Add any relevant screenshots/videos: n/a
   

5.   If you found a workaround, please add workaround steps.: in list view you can remove cards from main deck.
   

There are tons of this same type of post going back months. Why is this still an issue? Any fix yet?
