I am a new roon user, currently on the trial. I have invested in a ROCK running 1.6 and an Allo DigiOne with a rip running RoPieee as an end point into naim gear. I control with my iPad Pro (iOS 12.1.2). Very happy so far and am heading towards a lifetime subscription. However, I have noticed that the iOS control app is not as fluid as I would have expected, i.e scrolling jumps around a bit. Is this a known issue? This detracts from the potentially great user experience.
