Ringer volume resets to High
Whenever I have my bluetooth headphones connected to my iPhone XS (iOS 15.1), the ringer volume is really loud regardless of my current volume/ringer settings. I have disabled the Ringers and Alerts -> Change with Buttons option and adjusted the slider all the way down yet it still gets reset to full volume.
I have not yet fully tested this experience without headphones to confirm this isn't related.
