Freeze when use Qobus and Tidal on Volumio

Hi,

I’m totally new with Volumio, I have noticed using Qobus that when using more than 30 min pause
Volumio totally freeze. even when I delete the complete playlist.
also, see that on the device (zones) the last played album still been seen in the zones even when
I delete the complete playlist.

if I restart the player the zones is empty.

I use RPI3b and plugin NOW playing version 3.198

Thanks
