Some users are facing issues logging in with their Microsoft account

Incident Report for yasoon

Identified

We have identified an incident where a subset of users will see error messages when trying to login with their Microsoft account. Upon investigation we discovered that Microsoft seems to be rolling out a set of changed browser headers which are causing issues. We are working on a fix - in the meantime, re-trying to login for a few times seems to solve the issue for most users.
