iPhone Air volume buttons affecting notification tones and keyboard clicks despite 'Change with Buttons' setting off

"iPhone Air volume buttons affecting notification tones and keyboard clicks despite 'Change with Buttons' setting off: [...]This option was in fact turned to the off position. I have turned this setting on then off which made this setting perform as it should until I locked the screen and reopened it, it would then revert back to its original state.[...]"

Excellent job troubleshooting this!

Notification Sounds and Tap Sounds Decreasing:

Notification have their own volume options, Whereas taps don't. So, this is obviously a bug.

“Thank you, this seems to have been helpful. I have to say this has been the only issue I have had with the phone. I am amazed at how clever the iPhone and tablet are, certainly way better for me than android. I especially like the short cuts and automations, I have been playing with those all week.”
