Two iphones, iMesage notification issues
I have an iPhone 13 pro max for my personal phone and an iPhone 12 for my work phone. I have both phones set up on a single icloud account. I'm not receiving iMessage notifications on my personal phone, but they are coming through to my work phone. If I unlock my screen I can see the little red dot on my iMessages but the notifications are not coming through to my lock screen (I have the notifications set up to show in lock screen).
Could this issue be related to having two iphones on one icloud account? How can I fix it (I keep missing messages from friends and family).
Thanks
iPhone 13 Pro Max
