trying to set iPhone and iPad in 'App Center Listed Platforms'

Question

I just published a game for iPhone and iPad that supports Facebook, and now I'm trying to fill in all the App Details on Facebook.

But under "App Center Listed Platforms", I can't switch iOS iPhone and iOS iPad to 'YES'. It says 'this platform cannot be listed because it is either configured incorrectly or not supported in App Center'

I already set the iPhone and iPad Store Id in Settings to the correct one and still no effect.

Any ideas what else that could be? I already searched all forums but couldn't find anything. Do I have to do something in "Configure App Center Permissions"? I couldn't find any documentation that tells me what those inputs are for.

Answer 1

Turn on Single Sign-on under App Settings->Basic->iOS->Single Sign-on. (Echoing WizKid above).
