watchOS 26: Audio Playback Interrupted by Fitness Notifications Across Multiple Apps
After upgrading to watchOS 26, users report that when playing music on Apple Watch, if a fitness reminder is received, the music automatically pauses and users need to manually tap the play button to resume music playback. This phenomenon occurs with multiple music and podcast apps. This issue did not exist before the upgrade. We would like to know if this is an Apple bug or if there are any special development configurations needed?"

Unexpected Widget Refresh When Pausing or Playing Music in iOS App
Widget abnormal refresh My app is a music application. When playing or pausing a song, the status is synchronized to NowPlaying, and the app itself supports widgets. During testing, I found that when pausing or playing music, the widget triggers a timeline refresh, which is completely unexpected. However, switching songs does not cause this. Looking at Apple’s logs: By default 21:27:08.094490+0800 mediaremoted Set: origin-iPhone-1280262988/client-com.company.musicdev-10059 (music)/player-MediaRemote-DefaultPlayer setting inferred playback state from to By default 21:27:08.094607+0800 mediaremoted [MRDNowPlayingPlayerClient] PlaybackState changed from Playing to Paused for origin-iPhone-1280262988/client-com.company.musicdev-10059 (music)/player-MediaRemote-DefaultPlayer By default 21:27:08.094713+0800 mediaremoted [MRDNowPlayingPlayerClient] isPlaying changed to false for origin-iPhone-1280262988/client-com.company.musicdev-10059 (music)/player-MediaRemote-DefaultPlayer By default 21:27:08.111861+0800 mediaremoted Posted Active Now Playing Notification kMRMediaRemoteNowPlayingApplicationPlaybackStateDidChangeNotification for path origin-iPhone-1280262988/client-com.company.musicdev-10059 (music)/player-MediaRemote-DefaultPlayer By default 21:27:08.115550+0800 mediaremoted Response: handlePlaybackQueueRequest<B0BDBB4E-C539-4D39-B51C-718115EBD7C4 assistantd-2659 /M/L/AF/R[0:1]> returned for origin-iPhone-1280262988/client-com.company.musicdev-10059 (music)/player-MediaRemote-DefaultPlayer in 0.0005 seconds By default 21:27:08.119344+0800 assistantd Response: playbackQueue<B0BDBB4E-C539-4D39-B51C-718115EBD7C4 assistantd-2659 /M/L/AF/R[0:1]> returned <> for origin-iPhone-1280262988/client-com.company.musicdev-10059 (music)/player-MediaRemote-DefaultPlayer in 0.0010 seconds By default 21:27:08.122322+0800 SpringBoard Response: playbackState<63A30582-E3C2-4F4D-AC57-8E5841FAD568> returned for origin-iPhone-1280262988/client-com.company.musicdev-10059 (music)/player-MediaRemote-DefaultPlayer in 0.0005 seconds By default 21:27:08.126132+0800 chronod Observed com.company.musicdev stopped running for exempt reason: nowPlaying - remainingReasons: None By default 21:27:08.126285+0800 chronod [com.company.musicdev::com.company.musicdev.musicdesktopwidget:VisionWidget_medium4158108784:systemMedium:3758765227620768254:338.00/158.00/21.60:(null)~(null)] on local marked as requiring reload By default 21:27:08.126455+0800 chronod [com.company.musicdev::com.company.musicdev.musicdesktopwidget:VisionWidget_medium4158108784:3758765227620768254] Reload with configuration [systemRequest(sessionEnded)-immediate-free-1] By default 21:27:08.126854+0800 mediaremoted Response: handlePlaybackQueueRequest<ACF764D9-05A6-41FF-8BB5-8CB81A8BC163 assistantd-2659 /M/L/AF/R[0:1]> returned for origin-iPhone-1280262988/client-com.company.musicdev-10059 (music)/player-MediaRemote-DefaultPlayer in 0.0008 seconds By default 21:27:08.127960+0800 assistantd Response: playbackQueue<ACF764D9-05A6-41FF-8BB5-8CB81A8BC163 assistantd-2659 /M/L/AF/R[0:1]> returned <> for origin-iPhone-1280262988/client-com.company.musicdev-10059 (music)/player-MediaRemote-DefaultPlayer in 0.0016 seconds By default 21:27:08.128091+0800 wifid Response: playbackState returned for origin-iPhone-1280262988/client-com.company.musicdev-10059 (music)/player-MediaRemote-DefaultPlayer in 0.0115 seconds When the music state changes, you can see the widget is triggered to refresh. I want to ask if this is the system’s mechanism? I checked my code and there is no operation to actively refresh the widget when pausing or playing. Can this situation be avoided?
