Some problems I had with Snaps:
* Installed VScode. The terminal in VScode was in a different environment from the system terminal, so used different Python environments. Took me a while to figure out why installing a package was not working. * Installed Slack. When I click a link in Slack it opens a new Firefox process that does not have access to my normal profile, saved logins, etc. and is not shown as a Firefox window in the sidebar.
In both cases I uninstalled the Slack version and installed the "real" version.
