When adding Photos using the "Use Camera" option in either "Issues" or the "Photo" markup tool, whenever you take multiple photos in the same session, the photos do not retain the same order when you view them in the Issue or in Photos. They are given the same file name, which I think is the problem. You are forced to take one photo and select "Done", then re-enter the "Use Camera" option to keep the order in which you take the photos. This forces the users to hunt for photos, which is frustrating, considering you can't cycle through the photos in the active Issue without closing one and then opening another.
Improving the multi-photo functionality and enabling a scroll function in the Issues tool would be amazing!
