iphone not backing up on icloud or computer.
My wife's phone will not backup on the cloud or on the computer. She has 256 memory. I have updated, reset, phone and computer several times since Saturday. I bought new iPhone 15 and transferred data successfully after several attempts. Still can’t backup on either. iCloud backup adds another hour as estimated time and now says 15 hours and it has been backing up for 18 hours now
