As an aside to this I mute ALL notifications on my phone. I still get notifications of course, but they never ping or vibrate.
For important threads like calls or messages from important people/group chats, I have my watch vibrate.
Otherwise, I just go through my notifications once I have downtime.
I really like that system! How do you configure that only notifications from certain parties end up on the watch? As far as I can tell I can only filter on application. On iOS I can add “favourites” which get prio for calls and messages in Messages/Mail but not in other apps.
