After changing my primary email address, I can no longer access my Matrix account (a new one is created)
As the title says, my matrix account is gone since I changed my primary email address and deleted the old one.
Lost accounts can't be fixed or helped here. Consider creating a new account with a email that is free and not on some site or institution should one need a reset.
The matrix account is using Mozilla's own homeserver that is linked to my mozilla account. What do you mean that it can't be fixed? This is an issue with my firefox account
