hey,
Yes finally after 2 weeks the issue was resolved and they re-added all the megascan assets to my new email (accessible only from bridge). But, I had to send 2 separate support tickets (at the same time), saying the same thing, cuz the first one was not cooperating at all and just stopped responding when they got bored I guess..
You’ll need to provide any proof that you owned the old email address and that’s it.. good luck
