Hi @Redwine,
I just checked the behavior on my iPad + ROCK core and my squeezebox touch is still responding to volume commands as expected, even after being powered on and active for 17 days.
We just released a new Roon build, can you let me know if you are still able to reproduce this issue? Full details for the release can be found below:
If you are still able to reproduce do let me know and I can add that as a data point to your case, things should be calming down a bit on QA’s end now that the release is out and I hope to have some feedback for you soon.
