Producer unable to log in to Administration

One of my producers wishes to add some new products which they haven’t done before but the can’t see their Administration log in as shown below. Is there something awry with the E2E Permissions? I’ve tried to give them permission to do anything but nothing seems to work!

Are they added as a manager to their enterprise @SaraR ?

Yes @olivermuller, this is why I’m confused?!

Hi @SaraR permissions are working fine for me. Do you want to make me a manager of the enterprise that is having problems and I will see how it works for me.

This is resolved now. It was caused by the user setting up duplicate user names and then trying to use the wrong one to access his product list.
