Contributor login not working

Hi! I can't login to my contributor page. It shows a screen to add a mobile number secure the account. I already had a mobile number entered in my account. If I click the button to add the mobile number I get transfered to my Adobe Account (everything looks good there). Mobile number is correct. I already deleted the number and entered it again. Nothing changed on the Contributor page. 

The very good AI Chatbot tells me that there is no account for my email address!?
