When I do my workout in the morning I don't want to get any notifications. I put the watch on Do Not Disturb, Silent, and Theater Mode.
This silences all notifications from my phone ...
Except, at some point during my workout it vibrates me letting me know I've closed my daily activity goal and then again that I've closed my daily workout goal.
This seems like a bug.
I don't want to to turn off those notifications completely. I simply don't want them when I've told the watch not to disturb me.
