Your listing is showing as “reviewing”. If you paused the listing then it could possibly mean the invitation to sit hasn’t been accepted yet or the invite didn’t send. You might need to send the invitation to sit again asking the sitter to accept again.
When I go to my Sits-tab as a sitter, my confirmed sits show as in the pic.
(There is another tab for Open applications (not yet final) and Past sits, as you can see.
Thanks everyone. There was a delay from when the sitter accepted and when it showed in my confirmed but it is all good now. Thank you all for your help.
