Hello,
I have invited an external user and also performed some tests by myself and I cannot login to Business central as an external guest user.
I have sent the invitation, assigned the license, and synced between Entra and Business central user list correclty.
When trying to access through the Business Central portal it says that the account is not a profesional or work account. This appears also when specifying the Organization under Login options.
I don't know If I'm missing anything.
Note that the guest email is a gmail.com, but it works fine in the O365 portal.
Thanks.
