Just received my RS130 yesterday day same issue, very annoying… to say the least. Given the premium price of the transport one really expect seamless UI and experience. Its a bug in the ios app, i tested on my android and registration went thru without a hiccup.
Overall i think the UI of the RS130 is overhyped… given I replaced a Eversolo DMP-A6 the RS130 should be on a totally different level UI wise, its not.
Imagine my surprise when i attached the RSA780, and experience the lag of a 5k USD transport, pretty mediocre and pretty much regret getting the RSA780…
Remote is also not as snappy and responsive as I expect from a unit in this price range.
Luckily the sound quality is there, or i would have returned this in a heartbeat.
To me the cd performance is unacceptable at this price point, as well as having registration bugs in the app, which is vital to get the full functionality of the unit.
