I am going to try KDE Connect on my Zorin 18.1 VM and see if that works. Might even make a video of it.
I think I have found the 'issue' (difference) between Zorin Connect and KDE Connect - the latter has an additional package 'nautilus-kdeconnect' specifically created to enable files to be sent to supported devices:
I have posted elsewhere that Zorin Connect's GitHub page shows only 4 developers involved. If you visit KDE Connect's GitHub page you will see nearly 30 developers involved.
Note that if you are going to replace Zorin Connect on the Computer, remember to uninstall Zorin Connect from your mobile device, then install KDE Connect from the Play Store/F-Droid/App Store.
