Hello @Silversitters
I am more than happy to help with this one.
I do not believe there is any way to see when another member’s membership expires, but there is a relatively new feature that makes sure that any member that has a sit or sitter confirm has their auto-renewal turned on to cover the sitting period and to turn their auto-renewal off in their settings they would first need to officially cancel the sit in their inbox.
(demo screenshots only - not taken from an actual account)
So in theory going forward all sitting periods for both the sitter and owner should be covered by an ongoing membership and if the membership expires it will be automatically renewed.
I hope that helps alleviate any worries about your future sits.
