Hello, I have some answers to some of your questions, thank you for bearing with me while I found out further information.
@temba I am happy to update you that sitters can apply for sits where the listing has multiple dates and they will be able to apply to any of the dates that they are available.
@richten1 I just saw your comment about this further down the thread, that should be okay now, but let me know if it is not. Feel free to DM me the listing as an example. Thank you 
@Snowbird @systaran I raised your concerns about the current way owners need to cancel confirmed sits and the process around changing dates not being as easy as everyone would like. The Product team has said that this is currently being looked into as part of the new message and application (inbox) work they are doing and there will be future updates to make this easier.
Not yet, but this is on the product teams radar and is something they will be working on in the future.
@Snowbird thank you for your feedback around this, it is not exclusive to couples, it equally is solo sitters doing this as well, but I will share your concerns about the other couple member potentially signing up with a new account to the wider team. This is all good feedback!
Thank you for all of your feedback and suggestions. I am happy to answer any more questions that I can, but more product-related ones will have to wait until after the weekend now
