Many years ago when I first got an iPod I created an AppleID, which my wife and I shared for AppStore purchases.
When Apple changed the system, we created new AppleID to use for iCloud synchronisation for Contacts etc. We continued to use the original AppleID for purchases, which were all done through iTunes.
Now that iTunes no longer works for purchases I have been updating apps on line.
I wanted to install a new (free) app on my iPhone. This prompted for the password for my new AppleID, which I entered. I now seem to have one app on my new AppleID, and all the others on the original AppleID.
How can I configure my devices to use the new AppleID for Contacts, Calendar etc, but use the original AppleID for purchases?
Logging off the new then logging on the new seems to take forever, and wants to overwrite all my data.
PS The original AppleID has Family Sharing setup.
The iPhone is running iOS 10.3.2
When I go to Settings this shows
iCloud: new AppleID Store: original AppleID
below this it shows
iCloud: new AppleID iTunes & App Store: original AppleID Family Sharing: my name & my wife's name
I see no "person" icon on the top right, and when I click on Updates this prompts me for the password for my new AppleID
"Purchases" in the App Store shows
My Purchases Family Purchases my wife's name my name
The apps in My Purchases and Family Purchases my name seem the same!
