I've just upgraded to VERSION="21.04 (Hirsute Hippo) and Slack seems to have disappeared from both my Favourites and when I click on Show Applications.
It's installed as a Snap package and I can launch it but:
- how do I return it to
Show Applicationsand - how do I get the icon back in the Dock (it just shows a grey and white document there instead of the Slack icon)?
