No, it’s a new feature in preparation for our next-generation realtime connection, but ideally you shouldn’t see the ‘Background worker disconnected’ message at all.
As noted in the other thread, I suspect the underlying reason for seeing the ‘Background worker disconnected’ thread and the streams stopping could be related.
In the other post, you mentioned having the option set to refresh the media items. Are you referring to the ‘Auto refresh’ setting within the media item? If so, what is the refresh interval you have set? And is the ‘force refresh’ setting enabled too?
As a test, can you try editing the media tile instance on your dashboard and configure the ‘Action’ to ‘Refresh’? I’m curious if you tap that when the media items aren’t loaded if it will kick start them again.
