I raised the issue to my peers that cover New Outlook so hopefully they can help get more follow up on this issue. The best I can suggest is for those that have M365 to ask your tenant admin to open a ticket from the M365 portal. This will help get the issue investigated and escalated.
There is an incident today about this issue with Outlook Web Access (OWA).
Incident: EX930607
