Yeah I agree - the Activity tab and the DMs look like they are exact copies of the Teams interface. I mean, it's an intuitive way to display info but I don't see much design innovation with this announcement
Like periodically not recognizing why audio device on my computer. Or just not sending notifications sometimes. Or not recognizing @ autocompletes. Stuff like that. :)
As an old man I rely heavily on the read state to know if I have addressed a colleagues message. When this breaks I'm pretty much lost at sea. I have methods of tracking requests outside of Teams but really miss Slack's remind me feature. I've cobbled together one or two integrations with Teams and flow apps but they always lose authentication or something else breaks. Maddening.
