Thanks Waloop. I actually fixed my issue by deleting the Google Play Games app. I think it was trying to sync with the Google servers after login and for some reason it was failing. Customer Support still hasn't reached out to me to close the ticket but I've been able to play.
I'm still having the issue. Facebook Sync wasn't the issue. They switched my account to a Email & Password login and I removed the game from my Facebook apps. I was able to get a stack trace on another phone. Sent to Customer Service for help :| not sure what else to do.
