Sorting web galeries not working anymore

There is a cool functionality within Adobe Lightroom Web. You can publish Web Galeries easyily and very comfortable. Unfortunaley still years the funcionality is limited in sorting. Not even the simple sorting by name or date sometimes works and sometimes it doesnt. For example I did not find any way to sort the different Galeries in the overview. Sorting the images within a Galerie worked in the past, but the "how to" changed from LR version to version. Sameer from Adobe gave a good instruction a couple of years ago, unfortunaetly this does not worh anymore.  Can someone help please ?

1. How can I sort the different galeries (the list seem to be random sorted)

2. ho can I sort the images within a galerie (even when I sort them in LR C or in LR Web correytly it does not appear correctly in the public Web version).
