Nebula app spins on Android when another VPN app is "always on"

We had a couple of reports in Slack about the Nebula app spinning on startup: https://nebulaoss.slack.com/archives/CRWJJM52B/p1654479054750989

Hello, I have the Nebula app on Android 11. When I open it, the main page (where I presume sites are listed) continuously spins (loads). Adding a new site doesn't help. Restarting also doesn't help. I don't see any errors, it just loads forever. I imported the device and CA certificates as generated with the CA binary. Am I missing something?

Frank resolved it by ensuring there wasn't another VPN app marked 'Always On'.

Hey, I'm trying to connect my Android phone to my Nebula Network but the app keeps showing the loading symbol. Nothing changes when I'm adding a site

Sebastian reported the same thing, and removing another VPN that's "Always On" resolved it. https://nebulaoss.slack.com/archives/CS01XE0KZ/p1655052142562449

OK the problem was that I had another vpn app enabled as always on
