On my iPhone, in the Calendar app, I have both the US Holidays and the Birthdays calendars deselected. As expected, they do not show up on my calendar screens.
However, in the Calendar glance on my watch (Epix Gen 2), the US Holidays as well as Birthdays (fed from the two above mentioned DESELECTED calendars) are still showing up on my watch.
Any idea how to drill down and keep those from showing on the watch? There is no way to 'unsubscribe' from either, and neither are able to be deleted from the iPhone (13 Pro Max, running iOS 15.2).
