Domain limit was 50 domains. I added 3 domains many years ago, but today I got error `The domain limit has been reached for this account. You must delete one of the domains in order to add an additional.` and limit was changed to 1. I didn't find any news about it and I don't understand how the new limit can impact already added domains.
Try logging out and back in again.
Hmm...
I'm try relog and limit back to 50. Strange bug.
Got the same issue
Relog didn't solve it for me
