The chair is great, but the app needs some work. The 3D massage function needs labeling and the app could be more user-friendly. Perhaps an app manual? Also, the sales rep told me you can save 5 user profiles on the app, but I can’t find that option! Finally, the Bluetooth is a little screwy—when I try to connect my music (Spotify) and the chair app, two separate Bluetooth devices appear in my iPhone settings. And, I have to turn on and off my phones Bluetooth to get the music to play while using the chair app. Please update!!!
