This is the answer you get from Multcloud support:
If the account password is confirmed to be correct and 2FA is indeed disabled, but you still cannot add it successfully, we apologize that we do not have a better solution at this time.
For some days I am not able to re-attach my MEGA cloud to Multcloud.
'Some parameters are not entered entered correctly or you have activated 2FA'
Only parameters you can enter are Display name - Email - Password 2FA is not active (I can login to MEGA with above credentials without 2FA)
So.. paying to Multcloud for a service which is not working (anymore)
