I tried nordvpn, slack, and now github from android studio. Whenever I try to use an application that provides me a login link, I click it, log in on the browser, and click 'ok' or 'submit'. Then, either a terminal flashes up and quickly disappears, or nothing happens at all.
I've set both chrome and firefox as default browsers, so it's not that. I thought it was just a problem with the individual apps, but now that it's happened to every application, I'm not so sure about that.
Potentially relevant info:
- this is a brand new installation of ubuntu, on a new (to me) laptop.
- these are all snap packages, firefox was updated via apt upgrade
