Well, the update to 2.2.0 isn’t made for the prime 4… the display stutters, that wasn’t the case with 2.0.0… although there were times, but not as bad as with the current update …so back to 2.0 again…what a pity…maybe in the next update…and what I also noticed is that when scrolling on the p4, i.e. search for a track in the middle, the line on the deck has moved…?!
