The “Ready to Switch” screen without a continue button is a known issue that has been identified and a fix is already in the development pipeline for an upcoming release.
In the meantime, here is the workaround to get you back up and running:
Stop RoonServer from the [url=https://kb.roonlabs.com/Nucleus_Web_Administration_Interface]ROCK/Nucleus Web UI[/url], or quit Roon entirely if running on Mac
Navigate to your [url=https://kb.roonlabs.com/Database_Location]Database Location[/url] and rename the RoonServer folder to RoonServer_old
Restart Roon - it will create a fresh database and the "Ready to Switch" screen should now show the correct button
Restore from your most recent backup
If you do not have a recent backup, do not worry - keep the RoonServer_old folder safe. Once the fix is released in the next update, you can rename it back to RoonServer and your original database will be restored.
Great to hear it sorted itself out - thanks for letting us know!
The underlying issue is still on our fix list, so if the stuck screen ever reappears before the update lands, the workaround above will get you back up and running. I’ll go ahead and mark this thread as solved - enjoy the music!
