Can't use facebook login to intel with IITC on android

[SoundGuy]

When i try to log in to intel map using facebook it opens up the seperate browser app and tries to log in there instead of opening a browswer window winthin the up to login like it does when trying to log in with google
then it stays there and the login screen remains the same inside iitc

Same for me. FB login out of IITC Mobile is not possible, even after I changed the external link settings in the FB app directly it still doesn't work.
