GroupActivity: Dropping activity as there is no active conversation:

Hi, I am having trouble with Share Play working.

When I create and run the GroupActivity sample in SharePlay, I get the following message and GroupActivity does not work.

Dropping activity as there is no active conversation: <TUMutableConversationActivityCreateSessionRequest 0x2836731c0 activityIdentifier=jp.co.1planet.sample.SharePlayTutorial.SharePlayActivity applicationContext={length = 42, bytes = 0x62706c69 73743030 d0080000 00000000 ... 00000000 00000009 } metadata=<TUConversationActivityMetadata 0x28072d380 context=CPGroupActivityGenericContext title=SharePlay Example sceneAssociationBehavior=<TUConversationActivitySceneAssociationBehavior 0x28237a740 targetContentIdentifier=(null) shouldAssociateScene=1 preferredSceneSessionRole=(null)>> UUID=3137DDE4-F5B2-46B2-9097-30DD6CAE79A3>

I tried running it on Mac and iOS, but it did not work as expected. By the way, we are also trying the following https://developer.apple.com/forums/thread/683624

I have no knowledge of GroupActivity; I have Group Activities set in Capability. Do I need to set anything else? Please let me know if you can find any solution to this message. By the way, I am using Xcode 15.2 Beta, iOS 17.1.1 and iOS 17.3 Beta, Mac OS 14.2.1 (23C71).

Best Regards.
