Dear AMMackie,
Good day!!
Apologies for the inconvenience caused and please don’t worry, let’s work together on your concern and move towards a resolution path.
I understand your concern and I would like to let you know that I have tested the behavior at my end where I able to reproduce the same behavior as per the screenshot you have shared in the description.
In this situation, then I believe the problem should be reported and further investigated by related development team via collecting HAR logs because there is no any related service incident reported at the Microsoft Service Health dashboard.
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.
Reference: Get support - Microsoft 365 admin | Microsoft Learn
Note: To create a support ticket, you need to have admin privileges and if you aren’t admin of your Office 365 organization, please contact the admin of creating a new ticket.
Appreciate your patience and understanding. Have a great day!!
Best Regards,
Sophia
