Volume Up Button Not Working After Update

I agree with everything lobsterghost1 had mentioned and would like to add one additional step you could try:

Shut down your iPhone by pressing (and holding) volume down ⇣ ➕ the power button.

After approximately one full minute of powering off, press and hold the power button to power back on.

Good Luck! 👋🏼😉

I haven't seen anyone else suggest this happened after the last update. If the volume up button isn't working, schedule an appointment at your Apple Store Genius Bar and show the phone to Apple. Your tag line suggests you own an iPhone 15 Pro Max and It is still under warranty.
