I was trying to sign up for a ChatGPT account using my personal email address and I received the error message "This phone number is already linked to the maximum number of accounts." this is due to me previously having an account with my work email address - so I logged in with that account and deleted it in order to free up my phone number for use with my personal email address.
However I am still receiving the error message and now I am no longer able to access my old account!
How can I sign up again with my existing phone number?
