I know we can get the generic refresh schedule with snap refresh --time and information of last refresh for a particular snap with snap info <snap-info> command. Is there a way to get history of all the refreshes for a particular snap or atleast for the last three revisions ?
Not reliably, no. snap changes will list the update if it’s recent enough. snap info will tell you the refresh date of the current revision (that is, when it was refreshed to that revision).
