FCM Message Notification: MS Teams
Just now got 6-7 notifications saying- "Testing notification from Microsoft to investigate the problem." Can you please confirm is it truly Microsoft because I doubt it is as if it would've been truly...
This is the response I received from the engineering program manager:
We apologize for the inconvenience. We've isolated the source of the issue and applied a mitigation and confirmed that no further unexpected notifications are being sent to users Android devices. For more information please refer to incident id TM221041 on your M365 service health dashboard portal."
