The same thing happened to me. In addition, my do not disturb setting no longer syncs between my watch and phone and the setting is missing from the app. I think this started happening when my watch and phone app got an update about a month ago.
Yes this is a pain. It shines a bright light in my face every night. Do Not Disturb should disable the stupid gesture which also turns on at the slightest movement of my wrist and blinds my partner.
