I’ve had this problem on and off for years and it seems to be back in iOS 26. My notification volume keeps randomly spiking. Suddenly I’ll get a text and it’s as if my phone volume is at maximum. I don’t have alert volume linked to the buttons. The only way to fix it is a complete power cycle of the phone. Anyone else having this problem and, if so, know of a fix?
