I have two Adobe accounts, A and B. When I tried to change the primary email address of A to B, the system prompted that the email address is already in use. So, I logged into the B account and requested to deactivate it. After 24 hours, I logged into the A account and tried to change the primary email address to B again, but the system still said that the email address is already in use. Can this problem be solved? This is very important to me.
Additionally, I can receive emails normally from both A and B email addresses.
