Please fix distribution process for Ubuntu
The version in 20.04's apt is very old and has bugs. The version in snap is 3 months old, but apparently has issues that have been fixed. Unfortunately, installing the version directly from your site does not pick up the settings from the snap version (I am guessing because snap is sandboxed), so it is not easy to go back and forth from the snap to the downloaded version.
Snap or flatpak are a better solution than distributing your own deb packages. Please consider putting resources into maintaining the latest version in those stores rather than building your own, as it'll result in a more cohesive experience for end users.
