Team members are still marked as demo account even after payment
I recently opened up an account, changed my DNS so I can receive e-mail on my own domain. After that I created 3 new accounts for my family members (as Team members). I paid a full year on all 4 accounts using "Joint billing". All 4 accounts state that the contract term is due next year (July 2022), but only the first account is fully active, all other accounts stay in demo mode. This is a serious issue, since my MX records in the DNS for my domain already point to mailbox.org. In demo mode you can not add external aliases to the mailbox.org account (as in "firstname.lastname@example.org") So my family members currently can not receive any mail.
I already tried contacting Support/Helpdesk 4 days ago, but not reply so far. Did anyone else had this problem and has a solution? Better yet: if someone from Helpdesk/Support is reading this, please fix this, it looks like a serious flaw in your onboarding procedure.
