“Log in from the paired iPhone” coming up on Facebook Messenger app on Apple Watch series 4

Hi there,

I’ve never had this issue before, but when I tried to open the Messenger app today a message came up saying I have to log on from the paired iPhone. If someone messages me on messenger, the notification still comes up on the watch but I can’t actually open the app on the watch. Ive tried restarting the phone and watch, uninstalling and reinstalling the messenger app on the phone and watch and turning Bluetooth on and off on the watch and phone. None of these methods worked. The phone is updated to the latest iOS and the watch is on the latest WatchOS.

Someone Please Help!
