I'm not sure if this is the right forum for this question, but here goes:
My email address I've been using for years recently had a problem and locked me out for no reason (GMX).
I figured the problem would take several days to fix or possibly not at all, so I changed my email address on my Ebay account to make sure I could still get messages and use my account.
Fast forward a few days and the locked issue was (luckily) resolved. Now I tried to change my e-mail back in my account and it gave me an error, "Please try again later".
Maybe Ebay is having problems at the moment, but my concern is they may lock me out for attempting to change my address again so soon. Does Ebay have a time limit for changing your email address? Should I wait a few more days or?
