More info about snap updates and channels

From this page

Snaps are updated automatically in the background to the latest version, every day. This can also be done manually using snap refresh for either all installed snaps or by specifying a particular snap to refresh. You can also switch to another version of a snap by refreshing into another release channel, if the developer has published the snap in multiple channels. Valid release channels are stable, candidate, beta, edge and their name reflects the development status of snaps they contain.
