Hi,

I got my new Samsung Galaxy S5 yesterday, and have loved it so far, except I realized rather quickly that I couldn't sign in to any of my games using my Google account. Looking into the problem, I tried other games, but nothing seemed to work. Upon opening the Google games app, I realized that this wasn't a simple issue. The top area of the sidebar on the app that is usually used to switch between accounts was solid gray instead. All the sections including settings and excluding help & feedback either did not open or displayed the loading icon forever until I moved on to another section. I tried turning the app on and off, clearing cache, deleting data, but none of those worked either. My phone is a SM-G900M running Android 5.0 Lollipop.

Please help...
