Watch makes no sound on notifications..
Apple Watch, watchOS 3.2
Hi
If your Apple Watch is not delivering notification alerts as expected, the following steps may help:
If you have not yet done so, update your iPhone and Apple Watch to the latest software, starting with your iPhone:
In addition to the settings that you have already checked, also:
Check that Theatre Mode is not enabled on your Apple Watch:
Check that Do Not Disturb mode is not enabled on your Apple Watch:
Confirm directly on your Apple Watch that Silent Mode is not enabled:
Check the notification settings for affected apps. For example:
If the issue persists, the following further steps may help:
Close the Watch app and restart both your iPhone and your Apple Watch:
Unpair and re-pair your watch:
THere is the option to make the watch silent when you dark it with your hand. Just turn off this option and the notifications will work again.
