Notify when available feature in NEW Teams app

I think we will have to respectfully agree to disagree. I do see your point, but I'm coming from a place where users don't know and don't want to know how to use these things effectively and almost actively refuse to manage their notifications. We try, but some are thousands of miles away with a different culture and management structure, and there's only so much we can do. Some are sitting opposite and still complain about things they could manage. It's a means to an end for the job they actually do (which is nothing to do with IT or technology) - and many of our users are externals, so we cannot manage the Teams settings in terms of working hours showing, etc.
If all the users had your attitude, that would be fine and it would work, but they don't. All that happens when we try and educate them on managing their settings is that they'll complain to their bosses that they keep getting woken in the middle of the night by people asking them to get in touch when they're free, and because they're the big earners, that'll be that. More hassle on our side to deal with when there was a way that was working perfectly beforehand.
Also, it's caused me so much hassle moving to Teams 2.0 because of over 500 people asking for this feature back and using the lack of it as an excuse to not move from Classic. I've had to finally force the issue, which I didn't want to do. I don't think they're bringing it back anyway.
