I have a HiFi shop and I am having trouble all of a sudden (worked perfectly for quite a while) to where when I tell it to play anything when grouped (RP, Tidal, from HDD) it plays for like 10 secs then stops.
I have tried multiple things grouping only 2 things, grouping only the same brand, grouping different brands, so on. Everything I am grouping is Roon Ready.
Apologies for the delay in getting back to you here, I was out of the office last week and only just saw your update.
Are you still having the same issue occur? The next step here would be to verify if a Nucleus OS Reinstall or Database Reset helps, you can do both via the Web UI, but it is highly suggested to make a Backup of the database first.
