It worked for my test app! Thanks for the workaround.

Ok, thanks, ill test this now and let you know

Ok thanks so if I understand correctly I should set the bundle ID to match the app id, I.e both bundle ids set to T2VN6R4V2H.AtlasDrift.SnapTrail with the extension set to T2VN6R4V2H.AtlasDrift.SnapTrail.BackgroundDownloadExtension. I’ll give this a try and let you know.

Just to confirm — my test app's current bundle ID is AtlasDrift.AppleHostedAssetsTest. What specifically should I change it to as the 'no-adjective' form? Should the extension's bundle ID also change correspondingly (currently AtlasDrift.AppleHostedAssetsTest.AppleHostedAssetsTestBackgroundDownload), and does this require a new app record in App Store Connect / re-uploading my test aar?

Thanks will give this a try shortly

Appreciated, thanks
