Microsoft Teams users receive bizzare ‘FCM Messages’ notifications, here’s what happened

Microsoft Teams users were kind of bombarded with test notifications. Users reported receiving these test notifications for a couple of hours with one of them having received a total of 14 notifications.

The Microsoft Teams notification reads, “FCM Messages” with “Test Notification!!!!” at the bottom. Some users pointed out notifications saying “Testing notification from Microsoft to investigate the problem.” In some cases the icon for the notification was not the Microsoft Teams one but a solid circle. Tapping on the notification doesn’t do anything and the alert just disappears after that.
