I just signed up with GitHub Sponsors, and it seems to have created a Stripe Express account with my e-mail address, but not one that I can actually use to sign in to Stripe. I need access to a full Stripe account for other purposes, but when I try to sign up with my e-mail address, I receive the message “An account already exists with this email.” And when I try to recover the password for the account, I get the message “This account is linked to a business that works with Stripe. To view details, sign in to their website or app directly.” (The GitHub interface doesn’t provide access to the Stripe account password.)
The support person at Stripe suggested that I might be able to change my e-mail address to my personal address through the GitHub interface; sign up with my business e-mail address through Stripe; and then go back to GitHub and switch it back to my business e-mail address. I would try that now, but I’m afraid of making things even worse. In any case, the support representative said I should talk to GitHub.
It seems that my mistake was to sign up for GitHub Sponsors before signing up with Stripe directly. Any suggestions on how to recover from that?
