I have some doubt, can you please help me to clarify it? 1. Is this popup will only show on development and testflight build and not in app store released build? So for now we can ignore it. 2. Are we using deprecate pushkit Or PushKit will deprecate in new version of iOS ?

When app is not active or in suspended state, voip used to wake app. Our application is walkie talkie type app, so we can't report to call kit for incoming Push to talk audio, becuse of it we are using com.apple.developer.pushkit.unrestricted-voip and related certificate. As you mentioned we should stop using PushKit push in didReceiveIncomingPushWithPayload, then how will app wake up when user receive PTT audio, or new user request to join in call. As for below function, it's only triggered if app is in call. nonnull PTPushResult *)incomingPushResultForChannelManager:(nonnull PTChannelManager *)channelManager channelUUID:(nonnull NSUUID *)channelUUID pushPayload:(nonnull NSDictionary<NSString *,id> *)pushPayload
