I have the same problem as everyone else. I have a ipad2 16gb with the latest update 9.3.4. Anytime there is some special running, I can log in then get booted straight out. These crashes are disabling their revenue stream (which come from in-game purchases) so you'd think someone at EA would fix this but it looks like it's not a priority.
Someone wake me up once the silly sports event is over ; )
