Just to note, I spent time yesterday and today, working with Naim tech support, troubleshooting my Nova in connection with an open issue about Chromecast and volume controls.
While that issue remains unresolved* - I sent them a video demonstrating the problem this afternoon - I can confirm that otherwise my Chromecast has not “borked” on either 3.10 or 3.10.1.
*And it’s not a dealbreaker as the Focal/Naim app can still control the volume. Read the thread if you want details.
