Hello! So we may better assist you, can you provide some more information about device, IF version, OS, etc.
Inital thoughts…Visit Facebook on a desktop and log out, and then log back in, visit the applciations tab on the left side, remove IF and then try log in fresh with IF.
First off, Reinstall Facebook and IF and try again…
Device is iPhone 5s iOS and IF version is 16.13.0
Did you try restarting your device/IF?
I will try that thanks
Let me know how you get on…
I will try both thanks for replying so quick
All done that worked and I am now logged back in to my live account thanks so much for your help
Thanks :). Mark @LouDon16 post as the solution so the moderators know.
