What block list does the iOS app use?

So I’ve downloaded the app for iOS in the AppStore. It seems like it’s working without any problems but as soon as I enter the settings and click on advanced I don’t see which list is active. Is this a bug? I

Btw: which list would you recommend me using for iOS?

That’s a bit odd. Are none switched on in the “All” tab?

Also, the current default list on the iOS app I believe is OISD.
