Ionic Facebook Auth - iOS - App Not Setup: Still in Dev Mode -

i'm developing ionic app has google , facebook auth, (using firebase). android, have both working. for ios, facebook not working. here's screenshot:

and in case ask, yes, app live (and contact email set in settings):

i have added "ios" app in facebook developer console:

and far firebase concerned, added facebook app informatino config.xml:

ionic cordova plugin add cordova-plugin-facebook4 --variable app_id="<app_id_here>" --variable app_name="<my-app-name>" 

i've done humanly possible, , facebook should working on ios, it's not. once again, work on android, had add in "key hashes" facebook developer console work, depending on how signed app. ios, have no clue how apps work , there's no box put hash ios in facebook dev console, i'm not sure else can do.

update (solved)

so, when using ionic platform using firebase authentication, there's additional step needed facebook auth work on ios, , that's adding plugin "in app browser". command below. after removing 'ios' platform , running command, rebuilding it, facebook auth on ios works.

ionic plugin add cordova-plugin-inappbrowser --save 

did try add contact e-mail follows :

you need add contact email facebook app . select settings in left sidebar , provide valid contact email address.

and description of plugin stated in 1 of issue :

cordova plugin add cordova-plugin-facebook4 install latest version npm, not latest version repository.

to achieve last goal, need call cordova add github url

cordova plugin add https://github.com/jeduan/cordova-plugin-facebook4

source

update:

after long discussion after installing in-app browser plugin made work on ios

ionic plugin add cordova-plugin-inappbrowser --save
