Greetings theprovinces,
First, check to see which Apple ID is linked to the iPhone overall. You can do this by completing the following steps:
- On her iPhone open Settings.
- Tap on her (or potentially your) name at the top of the device.
- Verify the Apple ID shown and linked to the iPhone.
If the iPhone shows it is linked to your Apple ID, you'll want to reset the iPhone and then follow these steps to move the data from the older iPhone to the new iPhone: Transfer data from your previous iOS or iPadOS device to your new iPhone or iPad. Before doing so, you may want to verify the Apple ID that is linked to the older iPhone, as you may potentially have the same issue, depending on the transfer type chosen to transfer data between devices.
We hope this information helps you out.
Kind regards!
