My phone was never turned off, or on DND or anything else and I received the message but on her end it still says undelivered. How can I prove to her that I did not turn my phone off or anything else with it? And what time will it show it was delivered, when it first was sent or when it is actually delivered? Mine showed at 11:52 and she said it still said undelivered in the morning.
iPhone 12 Pro Max, iOS 16
I have to wonder if her cell lost service immediately after she hit send.
Anywho... Send her a screenshot of the thread as seen from your phone.
For further proof of what time you got her message, touch the screen and drag your finger to the left. That motion will reveal the times. While holding the screen to the left, grab a screenshot and send her the screenshot showing the times.
Everything that I've talked about her would prove delivery.
Is delivery the issue or is when you actually read the text the issue?
If her complaint is that you haven't read her text, then that's another deal.
You need to have "Read Receipts" enabled on your phone or at least enabled for her.
I hope that you find this helpful ;-)

If you receive messages on one device but not the other
If you have an iPhone and another iOS or iPadOS device, like an iPad, your iMessage settings might be set to receive and start messages from your Apple ID instead of your phone number. To check if your phone number is set to send and receive messages, go to Settings > Messages, and tap Send & Receive.
If you don't see your phone number, you can link your iPhone number to your Apple ID so you can send and receive iMessages from your phone number. You can also set up Text Message Forwarding so you can send and receive MMS and SMS messages on all of your Apple devices. "
