I'm trying to change my primary email address but it wont let me, instead it keeps giving me an error message saying it needs to be a valid email address... when it is a valid email address.

Same issue.

I had my secondary email address added, and then wanted to swap secondary to primary.

Now secondary is primary, but I can't change the secondary to former primary?

How do I get the secondary email address removed and the former primary on as secondary without error messages?

"There was a problem removing your secondary email address."

Same.
