Hello! I am using local notifications with a sound file. this works well with the iphone. as soon as i wear the apple watch, i don't get the notification sound anymore, only the default sound on the watch. how can i solve this problem? all pics in my notifications are correctly shown as well on the watch. thanks in advance for your help! regards, martin

Notification are (normally) silenced on iPhones when wearing a watch. Check in watch setttings on phone and see under notifications.

you may have to build a watch extension for Apple watch if you need custom sound.
