Our apologies for the delayed update for Ubuntu Linux users running Glimpse Image Editor as a Snap. We had to work through some problems behind the scenes to get our scripts for Launchpad and the Snap Store working again, but with some expert troubleshooting and assistance from Canonical we managed to work through the problems preventing the update from being released.

The update has been rolling out since 2020-09-28, and as Snaps are auto-updating you may already have it!
