WTH do notification tags STILL not work on Wear OS?

Seriously - all I want to do is to be able to send actionable notifications to my phone and watch, and be able to act on those notifications on either device, clearing from both devices once acted on.

Washing machine needs emptied? I want to send a notification to both devices with a “Done” button, and be able to click “Done” on either device, with the notification clearing on both. Can’t do that without a notification tag.
