Dear David Mercier2,
Good day! hope you are doing well.
After analyzing the detailed illustrations, you provided and conducting further investigations from our end, we have concluded that this issue requires more resources and expertise than our forum team currently possesses. Therefore, I recommend that you create a support ticket with Microsoft Support directly by following steps from this link: Get support - Microsoft 365 admin | Microsoft Learn
If you are not an admin, you can contact your admin to contact Microsoft support. You can look for the way to find your admin through this link: How do I find my Microsoft 365 admin? - Microsoft Support
Please accept my Apologies and I do feel regret for not resolving the problem and redirecting you to the related development team but the fix to your concern can be find out through the HAR logs and suggest you raise a support ticket from the Office 365 admin center, where the related team will investigate the problem further by collecting the HAR logs.
Once again, I apologize for the inconvenience this has caused. We appreciate your patience and understanding and thank you for your time and cooperation.
Sincerely,
Ralph Chawatama | Microsoft Community Moderator
