Comment 3 for bug 2043519

Hmm, to tell you , i have been using freetube snap from Rev.6 , i made custom settings and the fact that i can still use the snap as i configured earlier with latest revisions should make it clear that yes with upgrades older configs are synced.

See this doc to understand better, snapd do take care of syncing the configs of different revisions in the home directory.

Hope, that helps. 😃
