Changing the sort order of collections in Lightroom Gallery on the web

Hi all,

I am struggling with how to change the sort order of collections that I am sharing publicly on the Lightroom Gallery on the web, and would appreciate some help please.

I can sync my collections easily from Lightroom Classic to the web, and can see them in Lightroom on the web. I then want to use the 'Share in Gallery' function as shown below:

After selecting this option, the collection appears in a random order in the Gallery list, and I don't seem to have any control over the sort order :

 So my question is "How do I change the sort order of collections in the content list of my Gallery?"

As far as I an see, they are sorted by some random at, that does not reflect the name or creation date, and ends up with my gallery being all owver the place:

Thanks in advance folks
