I'm on a fresh install of PureOS that came with Librem 15. I'm unable setup an online accounts (google calendar, nextcloud microsoft exchange) via the calendar settings...each one says "Click here to setup" but clicking or pressing enter on them doesn't do anything.
I suspect there is a package missing probably due to a freedom issue. Still I think if that was true then either those options shouldn't be available, or there should be a way to install the necessary package.
