Hi everyone, thank you for bringing this up as soon as it happened. We’ve notified our team and this should be fixed now.
If you already updated to beta build 886, you should receive another update prompt shortly. Take the update and you will be back on the stable branch! You can also visit Settings > About to trigger the check for an update.
If you do not receive a prompt to update, you can manually re-install Roon from our website.
Now that the issue has been resolved I think we can close this out and keep discussion in the #support thread for those who may need help updating. We’ll also post any further updates about this incident over there. Link below, thanks all!
