Unfortunately, after applying that "remedy" I learned that Photo's no longer share foto's automatically on my wife & my iPh6's ... so we have to choose between 2 mutually exclusive options:
#1 - use one (1) AppleID and have the same library of pictures on both iOS-machines and on our two (2) MacBookPro's and on my (old) iPad but "add up our steps etc " in the Health_APP = un-workable & contra-logically-indicated
#2 - use two (2) AppleID's and have separate Health-APP-data (= logical & as should be) but have separate & maintain each our own picture-Photo-gallery's ...
I predict that one (1) Apple-expert-nerd will reply with the following advice:
use option #2 and create a shared album in Photo's & select/swipe/move (only) the images that you want to share with your wife ...
