I’m the phone app under listing my listing is gone. There is nothing there just a plus sign. When I click the plus sign to add a listing I can see my listing and it asks if I want to duplicate it.
@Nanie1 happened to me today also, and after a couple of hours the listings were back. I can only see one listing in the app though, but I can still see the calendars for both. I am assuming it is some update or something.
