If you’ve already confirmed a sitter but you’re both happy to change the dates then you’ll need to unconfirm the sitter first.
Just select ‘Unconfirm’ on your dashboard.
Select the date range you wish to change. Make the changes you need to then select ‘Save changes’. You’ll be asked to confirm this change. You can then ‘Close’ the date manager.
Then you can reconfirm the sitter. Just select ‘Confirm’ on your dashboard.
