I'm trying with iOS beta 7 and the updated SharePlay Developer Profile and I'm getting the following error: Error preparing group activity: Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service named com.apple.group-activities.conversationmanagerhost was invalidated: failed at lookup with error 159 - Sandbox restriction." UserInfo={NSDebugDescription=The connection to service named com.apple.group-activities.conversationmanagerhost was invalidated: failed at lookup with error 159 - Sandbox restriction.} The call to prepareForActivation() is returning .cancelled without any prompt on the device.

OK, turns out the issue is that the SharePlay Developer Profile still requires the com.apple.developer.group-session entitlement. The wording on https://developer.apple.com/news/?id=mxaeu6er made it sound like we should remove the entitlement, but perhaps that is only needed prior to submitting an iOS/tvOS 15 build to the App Store. Added the entitlement back and now SharePlay is working in beta 7.

Is anyone able to use SharePlay in the RC builds? The SharePlay Developer Profile doesn't seem to be working anymore. I don't even see the SharePlay Developer Profile in developer.apple.com/download anymore.
