I have a Trello account with one email address. I was invited to collab with a secondary email, so I tried changing my email account to accommodate the request. I kept getting an error that I needed to create an account with that board, but I'm also getting an error that I already own an account with that address. Yet when I try to sign in, it tells me that account doesn't exist....?
I had the invite sent to my primary email address, and I still cannot join the board (keep getting told that I need to create an account).
TIA
