Why does my accelerometer not work in test mode? Side Q why can I not open my Xcode app on my phone?

I just added unity ads in my iOS game with the services window. Now I cannot use my phone (The unity Remote app ) to control the Roll a Ball with the tilt controls. I can move the ball with WASD and I don't remember being able to do so before. I already tried to delete the ad code but that does nothing. Also I made a Xcode build so I could play my game away from home, now that app won't open. Both of these problems just happened on the same day, was there an update or something. Please help.
