Yep. That’s why I amended my bitter comment.
But still I can’t see the interest of targeting number_version since current link exists for the newer version.
That may be a problem for app’s that need data ( things like personal profiles, passwords ) which are not stored under number_version ( maybe this ? )
And that’s not optimal in multi-users context - where all users won’t make use of same app’s / same snap-app’s / same snap-app’s-version. In such a context you need to « tailor » .desktop files at each user’s level.
