I feel a little stupid not thinking of Siri, but I will say that this update made the manual turn-off a lot less clear.
I realized the following (for people who may ask this same question in the future):
- When Do Not Disturb is active on your phone, the lock screen displays a purple crescent moon on a white background icon beneath your date and time.
- When you tap this icon on your lock screen, it expands into a bigger bar that contains a triple dot menu on the right side, and the word On underneath the words Do Not Disturb. If you have a specific time parameter set for Do Not Disturb and you are within those time parameters, this section will also display your time parameter.
- Clicking on the triple dots will expand the bar into more details about Do Not Disturb and the settings available.
- Simply tapping the Do Not Disturb bar will turn it black and seemingly do nothing else. THIS IS WHERE I WAS GETTING CONFUSED: Tapping Do Not Disturb will turn it black and give no other clear indication that you have now turned it off. It does not say Off anywhere, it does not disappear. Not only that, but if you return to your lock screen after "un-tapping" you will still see a crescent moon icon (albeit now white on a black background) displayed beneath your time and date. Just today I lingered on the lock screen to see what would happen and it turns out that this lingering white on black moon simply goes away on its own after some time.
In conclusion: Thank you Idris for your help, I feel somewhat silly for not figuring this out on my own, but to be fair, this got more complicated and unintuitive.
Hope this helps some confused soul who like me just wanted a clear Turn Off button like before :)))
