Problem 1:
I played well with Tidal in mconnect App before updating the new system ver. 5.x for my RS 150B. After updating this new system version this morning, I started mconnect App as usual and ROSE was still appeared as one of the UPnP devices. ROSE was selected to play Tidal music. But it could not work properly and was asked to restart the system to obtain stable conditions. I started mconnect App again but ROSE was not found in the list of UPnP devices. I restarted the whole system and tried again. Unfortunately, the LED screen did not show anything finally and a bad smell was detected. My RS 150B was dead. I needed to take it back to the dealer for repair. 
Problem 2:
ROSE App of the new version, which is installed in my Android tablet, will close itself automatically.
Hello,
Would you try again after DLNA update?

Hi @ROSELOA
Can I just confirm that there’s an updated version of DLNA available in the latest version? I’m having a few issues with the current version and would like to check whether the this might fix them.
Please let us know what problems you are currently facing when using DLNA.
I will review your issue internally to see if it is a fixable issue.
I’ve raised this before, but specifically with Audirvana on my RS130 every few tracks the first second or so of a track is repeated. I wondered whether you’d updated the DLNA renderer software in the latest release which might have fixed this, but that doesn’t seem to be the case.

I am very sorry for the situation you are experiencing. I hope the repair processes will be completed successfully in a short time.
