Login Error Facebook,Page manager and Messenger

Hello Scremomango,

It appears you're having some issues signing in to these Facebook apps on your iPhone. Let's work together to see how we can sort this out.

1. Have you tried to restart your iPhone since you noticed this? If not, test that out: Restart your iPhone
2. Do you have any issues signing in to Facebook on their website on another device? Here is their link to check: Facebook - Log in or Sign up If you have issues signing in to their website on another device, then you'd want to contact Facebook using their Help Center website: Facebook Help Center In case you can sign in on that device without any issue, proceed to the next step.
3. Can you join a Wi-Fi network and try signing in once more to these apps?
4. If an app unexpectedly quits, stops responding, or won’t open will help to update these apps and reinstall them to test.
5. Check for any restrictions: Use Screen Time on your iPhone, iPad, or iPod touch

That should resolve the issues with signing in to these apps. If not, tell us more about what happened when you followed the steps above. Do you use a VPN, by chance?

Wishing you the best, take care!
