I understand your symptoms. However, it cannot be solved with current technology.
Hello Friend,
I don’t think it’s Rose’s fault!
I’ve had many sessions with Apple Support (AirPlay & BT data was pulled remotely from my then MB Air M1 and also from my current MB Pro M3Pro) and I had the same problem as you.
The problems you describe were all on my other network players. With my Rose, I don’t use Airplay / BT. All I need is my remote control (IR) and WiFi from the MB M3Pro to the router and from the router it goes to my RS520 via LAN cable.
I can only assume that it’s Apple’s fault, because after the MB SW update the problem was still there and still is, Apple probably didn’t do that much.
Addendum:
All of your problems only occurred with my Macbook’s. For example, if I used my iPhone / iPad everything was okay… all metadata, album art and the title time bar could also be seen on the displays of my previous streamers.
