i sent an iMessage & it didn’t deliver. Meaning the message had nothing under it, not even the red “Not Delivered !” However, hours later, it is still not delivered but when I sent out another iMessage, the second message delivered. Does that mean the first message I sent delivered along with the second message that delivered? Hope this makes sense!!
iPhone 7, iOS 13
Probably yes.
If the recipient is not in the internet coverage area the message though will reach the Apple server but not the recipient's device for which it is intended (assuming the recipient has only one device).
I've also experienced this bug that sometimes a message that was sent is not marked as a delivered one. And when you send another one, then it displays "Delivered". I asked a person I talked to and he said that he received both messages.
I think we should let Apple know about it. Don't hesitate to contact Support
