forwarding setup doesn't work
I have never been able to verify a forwarding action.
Following the procedure from the source account, I receive the verification email in the destination account and click "Verify". That causes a new tab to open saying that I must sign out of my current (destination) account and sign in to the source account. When I do that, there is no further activity and nothing has changed.
The source account is not currently in use, and I wish for any emails received in that account to be forwarded to my regular account. This is a paid business email account.
