Reposting my December 3rd reply which is buried by now. I’m very disappointed in Apple about this. All I can recommend is to send feedback, find a workaround and seek other options.
Also, considering how much this benefits developers, Apple should require them (at least the big devs) to offer this feature.
My post:
I’ve been reading up on this very frustrating issue, and have concluded that this isn’t a bug. I don’t think there’s any intention to fix it-unless enough people complain and it were to impact their long term bottom line. This was known about before release, and it there are a couple of reasons that they found it in their financial self-interest to take away such a useful feature (as small as it is, it was a huge help to me!). Sadly, I’ve slowly seen less “delight” and more disappointment in Apple products over the years. Especially since they could still be very successful without doing this kind of thing that hurts their customers to eke out more dollars.
Anyway, heres how I work around the issue for now. I turn on do not disturb for an hour at a time, and read my notifications when I turn back on. Has actually worked pretty well for me.
Seems that Outlook is better on a PC. My husband loves it on work computer, but I also found that you need a PC for some of the great features. It does look great on his amazing PC display...
