Kauia discriminates against older and poorer loyal customers

Kauai has changed their Loyalty program/app to a copycat of Discovery Vitality program, except they used inexperienced marketers and programmers, who developed a half baked program that does not work on older or cheaper Smart phones - at the same time, they closed down their existing app. Their uncaring attitude to their customers is also reflected in their arrangement whereby the only explanation of what the new Loyalty program is about is detailed in the new app, which will not work on my Samsung device (i.e. no choice given to loyal customers). Anyone with experience in developing apps knows that the bulk of the work is in modifying the system to work on the various devices, platforms and operating systems that consumers use. Kauai clearly was trying to save money by using cheap developers who developed a program for Android 10 and above only, catering only for expensive and new devices and leaving everyone else without any app whatsoever.
