Community posts lost when changing email address?

Anyone else have an issue with all community posts/requests, etc lost when email is updated in profile?   My current email address will be going away soon, so I changed to my new address, but when I log into the Zwift community all my past history is gone.  Just wondering if others have experienced the same problem.   I have an open ticket, but so far Zwift tech support can’t solve the problem.  Curious whether this is isolated to my account, or whether its a general glitch.  (Of course I’m kicking myself now for ever using an email address that could go away…arghh!)
