Owner account issues using an email distribution group


I just deployed Duo a week ago and have yet to been granted access to the support portal for a paid account under the MFA tier. I am working with support through email, but am wondering if the issues I’m having are due to my owner account being an email distribution group instead of an individual inbox.

Example - distribution group name and owner account duo@<domain.com> forwards to user@<domain.com>. I need the Support Portal to be associated with duo@<domain.com> but there appears to be some internal issue with this.

Are distribution groups not supported or not recommended? I’m getting to the point where I may just cancel and create a new account and start over using a separate “real” inbox email address with my domain but wanted to check if anyone else has experienced this before pulling the plug on this deployment.
