Login Issues (Version Mismatch)

I play about every day and things have been running good for years. Today… I got a “Version Mismatch” on the login screen. Version is 5.0.13.92028 and the region is Americas. Am I missing something. I downloaded the “Public Test Realm” but that didn’t seem correct. Any help? Thanks.

I am in the same boat. Have they reached out to you yet or had any update?
