Duplicate push messages on Android only?

Anytime I set a routine or CoRE piston to trigger a push notification, I get duplicate notifications, only on my Galaxy S7. I also use an iPad and the same actions only trigger a single notification. Anyone else having this issue? Any idea how to resolve?

Only 2 !!! I’ve been getting 4-6 of every one for about the last week. Somebody unlocks & relocks the door and I get enough notifications to wake the dead.
