Just a quick note here while we get everything cleaned up. Build 886 beta is exactly the same as build 884 stable save for a one-line code change related to a bugfix we were testing. If you took the 886 update you can rest assured that there was nothing in that build which will cause any problems with your Roon core.
We have corrected the issue with the update server which led to this problem and you should see prompts to move back to build 884 stable shortly.
We will post later with a brief summary of what happened and the steps that are being taken to ensure that it doesn’t happen again.
Sorry for the confusion that this caused and we appreciate your patience.
