Thank you for your comment, yes when apple ID is the same, the photo simply pops up seamlessly without notification.
In this case however: It is not the same Apple ID, that is why there are AirDrop notifications involved, as explained above in fact The iPhone SE actually belongs to my son, and that is also why it is so annoying, we use the feature a lot, and it is very hard for him to find the notification because no pop up.
In the notification list there is no AirDrop application with alert settings to choose from. I can’t understand why it is occurring. When i airdrop the other way around from my SE to 8+ there is no problem. I have AppleCare+ I guess I should call them, I was just checking here first.
