Facebook Messenger shows 1 unread message but none seem to be there.

[Windows Central Question]

No unread Messenger messages show as unread on my iPad or PC but always 1 on Lumia 435.
I have uninstalled Messenger from my phone and reinstalled. After a few minutes the dreaded '1' re-appears.
Any ideas, please?

Same here. Somehow, the Live Tile updates itself, and the '1' disappears by itself.

This just tells how much 'attention' the developers put into the development of Messenger for W10M. It's a minor bug, sure. But imho it should've been fixed long ago.
