Can’t log into the Facebook app

Hi, has anyone experienced a login error when trying to log into the FB app? I’ve been experiencing a login error “An unexpected error has occurred. Please try logging in again”.

I’ve tried contacting FB but no one gets back to me and have done the following troubleshooting to no avail:

1. Turning off my phone and back on
2. Resetting the network settings
3. Resetting locations & privacy settings
4. Deleting the app off my phone and reinstalling it
5. Logging in from another browser (can do so successfully)
6. Having a few different people try logging in on my app

Is there any other suggestions out there?
