Messenger Not working

Hi, in Apple Watch Facebook messenger is not working. When I click it ask me to login from paired IPhone. I did in many ways but still showing the same message. I reset my watch as well but not helping. I uninstall And reinstall the messenger In both phone and watch but not working and showing the same. Can you please help me out? Also why wattsapp logo not coming to my watch and not able to access? Only getting message notifications.

Thank you.

Anna
