Facebook Messenger will not connect to network or open
A few days ago, and I am not sure what triggered it, but suddenly Messenger won't let me sign in nor open the app on my iPhone 7 plus using the latest IOS software update. I have tried:
Force closing the app
Rebooting the iPhone
Trying to get into Messenger through the FB app
Resetting the network
a full reset of the phone.
nothing works
I just continue to get fatal error messages:
