When I first upgraded to iOS 13 on my iPhone 7, the initials displayed in the Health App suddenly changed from RD (which is correct) to JS. I figured this was a minor bug which would be eventually corrected, but the latest version changed it again to KS. This seems to be the app randomly choosing names from my contact list. Does anyone know how to change the initials or to force the app to select the (correct) initials again ? This is only an annoyance, but I can’t see in my searches on the forum that anyone else seems to have an issue with this ....
