ad bug

So I've encountered this glitch where this mystery ad haunts my screen. I can't remove it, deleting the app and downloading it again doesn't work, and it stays no matter what I do. It doesn't impact my ability to click on things, it's just in the way. Update: forgot you can reboot your phone...

So just this morning when I logged into Skullgirls Mobile everything was fine, but after awhile I kinda noticed that it sounded like 2 song where playing at once. I went to the settings menu and turn off the in game music and there was indeed a second song playing, weird relaxing type of music...
