After unpublishing a snap,
snap info was not finding it anymore:

Fortunately, I was able to revert the situation by going to the dashboard, then publishing the 267 revision to edge (where it was not before). After that I published 274 to edge again.
The situation was fine all the time from the dashboard, but not when running commands from the command line.
