I updated to the latest build and this happened...Also can't join battles or spectate them.
This is happening to me too
Does restarting the app solve the problem?
No, I've tried that twice before.
Delete and reinstall?For some reason there's a version mismatch between components, it seems to be using a cached version of the UI. A reinstall should work.
That worked and thank you for the help.
I've now updated the caching policy and did new iOS build (170322.2350) that should fix this.
