2 weeks ago, I had the same problem. Where I can't connect to pvp. I tried logging in after the game updated. But it stuck on the title screen. On the 3rd attempt, the game crashed and sent me back to my phone's home screen. Then I got a garbled mess of letters on the 5th or 6th try. Now I am forced to reinstall the game again.
This is from the last time this happened, but it looked something like this.
