Hello 
On my account setting page when I click the Facebook connect button or try to log in with Facebook seems it starts to readirect to Facebook but after a second it dropped the loading process.
It’s really odd the other associated account connect buttons works fine and redirect successfully. The other strange thing is only happens on my mobile and only in Chrome browser. On the other browser I tried (Firefox, Edge) is working fine and also on desktop it works fine. I tried to clear chrome cache and reinstall the browser has the same result.
I also checked the console when I tap the button on mobile and it’s clear, no error.
Huawei P20 Pro
Android 10
Chrome 118.0.5993.111
I categorized this to support as I don’t know the problem is maybe in my device. Can anyone check this?
Thanks 
Update:
It seems when I close the Facebook app before tapping on connect button it try to redirect and open the Facebook app.
So I uninstalled the Facebook app and tapping this way the button seems successfully redirect to Facebook website.
