Greg Knauss, on App Store Review rejecting release notes, mentioning the iPhones XS and XR by name:

You’ll note that I didn’t mention the names “iPhone XR” or “iPhone XS Max.” However, Apple again responded with a rejection […]

Apple apparently considers referencing the devices that an application is designed to run on not relevant to its functionality.

So on September 20, 2018, I squared my shoulders, modified the release notes again, and resubmitted the app:

A change was made. We can’t tell you what the change was, because that’s disallowed by Section 2.3 of the Program License Agreement. But we can’t not tell you what it was, because that’s disallowed by Section 2.3 of the App Store Review Guidelines. This leaves the app in a state of quantum indeterminacy, and the waveform can only collapse when someone doing App Store reviews stops observing it.

Apple — sensing that I might not be taking the process seriously — responded […]

We had the same situation and I was as baffled as Greg. Hats off to him for standing his ground and fighting absurdity.
