Sharing the Wi-Fi Password with both iOS and macOS devices under the Same Apple ID is not available for me. I can share the the Wi-Fi password with other person if we if we are registered in the phone book both. However, I can't share my Wi-Fi password from my iMac to iPhone if I open both Wi-Fi and Bluetooth. I opened the Wi-Fi password type screen on iOS, hence a pop-up don't pop-up on Mac for allowance.
What is the main reason ?
iOS 12.1.4 & macOS 10.14.3
