I'm going to continue posting in this thread for the same problem, but I can make a new one if that would be better ..?
I am using an iPad (ios 9.3.2, iPad Pro) and I am unable to login. I hear a faint click when I hit the login button, then nothing. No prompts, no new windows, no logging in (which is what it was doing up until the last patch). My P.A. says VER-514-20160701 and my PFID is blank.
I tried hard-resetting the iPad and I tried deleting then re-installing the app. I still get the faint click when hitting the 'link social gaming network' button and nothing else happens.
