I already have an account on the service and wanted to change the email address linked to it, as I’ve set up a new primary email address. I changed the email address in the settings, and an email with a link arrived at the new address. After clicking the link, I was asked to log in (for some reason), so I chose the option to log in via Google, after which it simply created a new account, unrelated to the previous one, on which I had wanted to change the email address. I deleted the newly created account and went back to the old one to resubmit the email change request – as a result, I can no longer create or log in to an account with the new email address (“The allowed number of accounts is exceeded. Please use a different email address.") and I cannot receive a password reset email to the new address (if, as the notification states, an account for that email address already exists).
I have already given up on the idea of changing the email address on the old account, but how can I simply create a new one?
