I'm thinking of getting the XR as my secondary phone alongside my XS Max. My XS Max is my primary phone, the XR is going to be used mostly for work. Can someone tell me if the following is possible or not? I want my Apple Music library to appear on both iPhones. I want to backup WhatsApp conversations or app data on a separate Apple ID (I have an alternative Apple ID available). I want the apps I have purchased on my primary Apple ID to be available on the XR. I only want my secondary Apple ID to appear as iMessage/Facetime ready on my XR. I want my XR to appear under Find my iPhone on my primary Apple ID. It's essentially a mishmash of 2 different Apple IDs.
