@pietkuip on the app its simple. All past sitters are listed- with their review for the HO or a blank space below. Just click on their profile pic and find the HO review for the relevent dates. The only time you won’t find a past review for a sitter is when the HO did not write one.
If you are looking only on the website -only past sitters who reviewed the HO are listed. So if the sitter did not review they are not listed- so you have no way of cross referencing. Always check the app.
