Re: facebook disabling embedded browser login
Hello,
There was this Facebook blog post here that said they are no longer accepting android embedded browsers for security reasons. The message says you may be able to continue by updating the app so if you have an update available that might be able to fix it. Otherwise I would contact the support team.
You can contact the support team by going to settings, then help, then contact us. This will take you to the support site where you can explain your issue in greater detail. You will likely need your player ID which you can find by going to settings, then help, and your player ID will be at the bottom.
Hopefully they can get this sorted out.
Good luck!
