"unexpected error occurred" message displays on my Facebook and Messenger apps on iPad

I had this problem too. I read many posts about this issue, tried various workarounds, and found a method that worked for me. Maybe you can try it:

1.Completely delete the Facebook and Messenger apps.

2.Backup your device (which doesn't have Facebook and Messenger).

3.Restore your device to factory settings.

4.Go through the welcome screen without signing in with your Apple ID.

5.Once you reach the homepage, use a different Apple ID to sign in to the App Store and download the Facebook and Messenger apps.

6.Log in to your Facebook account. (This worked for me.)

7.After that, you can sign in with your real Apple ID and iCloud.

Before attempting the above method, I recommend that you simply delete these apps, log in with a different Apple ID, re-download the apps, and try logging in to your Facebook account first. I didn't try this because the above method worked for me, but I think logging in with another Apple ID without resetting to factory settings might work too. It's not too hard to try it first.

This morning, the messenger and facebook apps were working a couple hours ago but suddenly, I’m being made to login again and when I do, the password or reset request doesn’t go through or I get “ unexpected error occurred”

here is what I’ve tried so far

checking for needed app updates ( apps are up to date)

I’ve tried restarting the device

uninstalling and reinstalling the apps on the iPad.

nothing is working and Facebook support is useless

Faceboook issue, not Apples. Wait until they fix the issue. Probably due to the last update they pushed out.
