Iphone 11 Sounds and Haptics turns my bluetooth headset volume down
Since the last software update, every time I use my bluetooth headset, my phone will randomly through the day turn my volume down, with a message that "Sounds and Haptics has turned your volume down". I don't want it to turn my volume down, it's not nearly as high as it seems to think and on top of that I only use one earbud, so it's at a comfortable volume for what I'm doing. But there is no setting anywhere that I can find that prevents it from doing this.
I've gone into "Headphone safety" and switched the "Reduce Loud Sounds" to OFF, but it still does it.
I read somewhere that "Ringer and Alerts-Change with Buttons" might have something to do with it, so I switched that to OFF, and it still does it.
This is really tiresome and not a setting I want, but there seems to be nothing anywhere that helps! Why?
