I have Ubuntu with KDE Desktop. I have a problem. I have installed Gravit Designer (Appimage). All Ok but the files of gravit (.gvdesign) i can’t open. if I double click on them, this are open with application “ark”. I only can open if i open gravit and i access from menu open.
This is a error of Gravit that don’t generate mime types correctly.
My versión of Gravit is 1.2.1.
I attach video where showing the issue.
