I so love being back on Pebble with my PT2. There is only one option I really miss from my Pixel Watch and that’s muting notifications (and vibration) on my phone when I wear my watch. Feeling the notifications on my watch is enough, I don’t want my phone to also notify me.
I suspect that hooks deeper into Android than the Pebble app has access to
Though maybe it’d be sufficient to let the Pebble app to change system settings. That way it can just set the notification volume to 0 and set no vibration
