I have three battleground arenas that have been unusable for over a year. I figured I could purchase a new one, and it could resolve the issue. But it did not. Now I have four unusable stages. My collection is always stuck with one new stage available. I have tried restarting and logging in from my computer, iPad, etc. Logging out of the account and logging back in. It is frustrating that I have items I purchased and cannot use. I have made multiple tickets; this time, I am told to leave this on the bug forums.
