Hey, Thanks for reaching out to us.

When you select Managed domain option for device enrollment in Android Enterprise, you will have to use a Gmail account that is not associated with G Suite.
Whereas when you choose the Google Domain option, the account you use should have a Gsuite account associated with it.

Please use the help link for info regarding configuring Android in the Enterprise using G Suite in Hexnode MDM.

Cheers!
