I have upgraded to `Xcode 10` on `High Sierra` and now the [Rewarded Ad example project][1] from AdMob complains that `com.apple.commcenter.coretelephony.xpc` is not working correctly.

Is there a new entitlement that I have to enable? I am searching for hours without any clue.

**UPDATE:**
This only happens from the simulator. On the device it works fine. They must have added a new restriction.
