I think Apple will put out a patch that resolves this newly introduced nuisance, and it is a major nuisance to be sure. Not only does it come up so often, but it also positions itself at the top so it bumps down everything else. A problem made worse if someone is using Accessibility features to make text larger (and thus, the boxes that hold the text are larger).
I have become accustomed, for years, to enabling DND so the phone doesn't buzz, beep, and otherwise distract me or others I'm in a room with. Yet I still check my phone lock screen for messages or calls that are coming in while I'm in DND mode. To contend with that unnecessary alert is very annoying.
And also, the **** thing is totally unnecessary from my view. Here's what I mean: the phone is locked, and the screen is off. If calls/messages came in and you didn't hear them, then being reminded of that fact as you bring the screen to life is achieved by the fact that there are new calls/messages on the lock screen that you hadn't seen before, so having an alert that also says you're in DND mode is completely redundant and useless.
Further on that point, I acknowledge there are people who didn't know they were still on DND mode, but I have to shake my head because you'd have to be a nitwit not to be able to recognize that fact when you brighten your phone screen and see that you had missed calls/messages. Again, the "DND is on" alert is really just useless for all intents and purposes that I can see.
Apple can solve this problem by allowing users to decide if they want this alert or not - that lets everyone decide on their own and solves this problem perfectly. Or if it must be the way it is now, maybe just have some kind of icon somewhere, or a different color tone on the time, or something other than this obtrusive alert in the notifications area.
So anyway, now that I know for sure there is no feature to fix this I will patiently wait for Apple to wise up with a patch.
And to somewhat answer a question posed earlier about whether Apple monitors these forums: I don't know about Apple specifically. Usually companies do not, simply because they don't have the resources to do it consistently for all threads in all sub-forums. Larger companies sometimes do: they hire full-time forum moderators that double as 1st-level support agents and the whole forum is set up in a way that threads are flagged as "needing an answer" and mods+mvp's can be configured to be alerted to unresolved questions so the forum doesn't become a black hole where questions go to die.
But when you cater to the consumer market, it's usually not done. Respectfully, but the majority of consumers are uninformed complainers that don't give consideration to what they're saying before they belch their ignorance onto a forum thread. But those are intermixed with intelligent consumers so my perspective is not black and white here. Fortunately those on this thread have so far all been of the latter type. But keep in mind, the product management and quality teams from these organizations usually DO scour the forums looking for common sources of complaint or feature requests, so even though you don't have the satisfaction of knowing your voice was heard, if you start a thread that you know will catch their attention, it's a fair bet it'll be read. Of course, mentioning your particular issue on the 13th post of an obscure thread will not likely get any attention. Nor will large posts, such as the one I just made 😉
