Perhaps VDH does support the site. It would be helpful if you posted a proper problem
report. Take a look over here:
https://groups.google.com/g/video-downloadhelper-q-and-a/c/BzPLK2YyL-s
Look for the references to how to report a problem, click through to those, read what's
there, & follow the advice you find there. Then somebody else (possibly me, possibly
others) could try the site & see how we get on. Maybe we'll confirm your claim that VDH
doesn't work on the site. Maybe we'll discover VDH works just fine on the site. But you
haven't posted enough information for anybody else to determine what's up with this.
