At attempt to download with AppStore Roon Remote - the program isn’t loaded. Writes that isn’t suitable for this device. iPad model (3rd generation) A1430. Why?
Roon Remote for iOS requires OpenGL ES 3.0 support meaning iPad Air, Air 2, Mini 2, Mini 3 and later.
Roon is not compatible with that device as its hardware does not support OpenGL ES 3.0, have read of these topics where it is discussed in detail.
Roon 1.1 Is Live! esp. the iOS section.
