Push notification... usually. Lets check

My first response, Incorrect.. All settings were in place but so I check... messenger is not included in the count in mobile top bar, only notifications...

• On desktop, both notifications and messenger messages are counted properly.
• On mobile, only notifications show in the red badge (on profile pic).
• Messenger alerts are excluded from this unified count in the mobile top bar.

I have the workaround should you wish to display messenger on mobile as well.
