Sometime a couple of months ago, I saw a thread or article discussing this. When I checked (S24U and Buds3 Pro), I saw that the buds no longer appeared in the Wear app. However, that seems to have returned, and I now have my Watch 7 and both Buds pairs appearing in the Wear app. (Buds still appear in BT settings) I don't have a good answer for you. Serendipity, perhaps?
