Can I switch to slower Tidal streaming rate in roon

To save download usage I would like to switch Tidal between normal and HiFi/MASTER when connected through roon

Do you have limits on your downloads? You could subscribe to the lower tier of Tidal.

I want to switch between low and high quality, if roon can’t do this I’ll have to use the Tidal interface when I only need low quality,

I’ve only switched quality via the Tidal subscription option. Not certain if that capability exists within Roon OS.
