Groupy doesn't work with Windows 10 multidesktops

Was led to believe Groupy worked with Windows 10 multidesktops.  I tried the Groupy free trial and found out it doesn't work with Dexpot (would be nice if it worked with Dexpot, as I prefer it to Windows 10 desktops).  Your Groupy web page says it works with Windows 10, it doesn't.

After grouping 3 windows together and going to other desktops, when I go back to the desktop with the grouped windows there is no longer a menu bar with tabs to select windows in the group.  Tried this several times and the menu bar always eventually disappears.

I should add that just going to other desktops and immediately switching back does not cause it to disappear.  But, when I work in other desktops, going back to the grouped desktop, the menu bar is gone.
