I have removed Gradio from the Snap Store. I am not able to upload new versions of Gradio without using Ubuntu.
All the time it was still possible to publish Snap packages via the snapcraft.io web interface, but this option has now been removed. You are forced to use snapcraft, which is only available for Ubuntu systems.
There were technical problems with Snap. Users were unable to install Gradio without using the terminal (the GNOME runtime does not download itself automatically when using the ubuntu software center).
Unfortunately I have to say that Flatpak/Flathub is the better system for my purpose.
Gradio will continue to be available on Flathub (also for Ubuntu users).

Ubuntu wants to keep snap for itself . They will end up with no one using it anymore and they will stop it's development (for the desktop apps)....
