I have start new live activity with push notifications,but sometimes this code"activity.pushTokenUpdates" can not callback to me,so I can't update the activity with push notifications. And I already click “Allow” button in my live activity widget.How can I solve this problem. Here are my code： fileprivate func observeLiveActivityForRemoteCreate() { // obverser pushToStartToken Task { if #available(iOS 17.2, *) { var beforeToken = "" for await pushToken in Activity<HLPlatformActivityAttributes>.pushToStartTokenUpdates { let pushTokenStr = pushToken.map{String(format: "%02.2hhx", arguments: [$0])}.joined() // avoid send duplication if beforeToken == pushTokenStr { return } beforeToken = pushTokenStr // send pushToStartToken to service await HLPlatformLiveActivityBridge.registerLiveActivity(withAttributesName: self.activityAttributesName, pushToStartToken: pushToken, seq: seqCreate(), pushType: .jPush) } }else { // Fallback on eralier versions } // obverser live activity update Task { for await activity in Activity<HLPlatformActivityAttributes>.activityUpdates { if let businessLiveActivityId = activity.attributes.businessLiveActivityId, let liveActivityId = activity.attributes.liveActivityId { Task { var beforeToken = "" for await pushToken in activity.pushTokenUpdates { // here the problem：sometimes pushToken not update to me let pushTokenStr = pushToken.map{String(format: "%02.2hhx", arguments: [$0])}.joined() // avoid send duplication if beforeToken == pushTokenStr { return } beforeToken = pushTokenStr // send pushToken to service } } Task { for await stateUpdate in activity.activityStateUpdates { if stateUpdate == .active { // live activity create } } } } } } }
