P:: Shared Collection Limited to 100 Photos When Reverse-Sorted

When I sync a collection with more than 100 photos to Lightroom Mobile and share that collection, I have no control over the default sort when another person visits the shared link. Using the default sort (ascending capture time), the other person can scroll all the way to the bottom of the page (which initially loads only 100 photos) and it will proceed to load the next 100 (or so) photos. However, if the sort was toggled to reverse, the first image that appears is the 100th photo instead of the actual final photo and all photos from 101st onwards are missing. Scrolling to the bottom has no effect in reverse sort.

I tried communicating this over chat support and it took the support staff over an hour of my time to understand the problem. He then kept insisting this was a problem with the software on my computer and insisted on collecting logs from me. It is frustrating enough to have this small problem, even more so when Adobe support staff cannot comprehend issues with their own software, but outright abysmal when they can't even identify that this issue is with the web service and not with my computer.
