The app was made assuming you have a relatively continuous data stream. Your data is very sparse with respect to time. I was able to get it to work with the properties shown in the picture here, since you have more regular data over this range (today). If either the section you select for comparison or the base region is empty of data, the comparison will fail. Thanks for the feedback on the app though! Ill have to think how to accommodate your use case given the architecture I’ve used in the app. The code is there in File Exchange though, so feel free to suggest a good solution if you have one.
