I know that it is in preview, which is why I'm so upset about the idea of adopting it at this point. Seriously: I'm ranting about this product because it is unfinished and unpolished, but obviously the blame for adopting this thing lies in this company. I wouldn't criticize it that much if I'd be able to watch the painful first steps as a bystander.. You use the web client? I assume you mean teams.microsoft.com? The URL that I see nowhere in my notifications etc? Every notification mail links to a landing page that wants me to download a "native" client (even if none exists for the platform I'm on). Notifications also never include any details: They say "Look, you missed stuff on our service. Come back!" instead of actually.. providing any information. The web client has quite some bugs, a fun one is opening a document (which embeds a 365 viewer, I guess) and resizing the window. Last I checked the document view cannot grow. Lots and lots of issues like that. That API site? Yes, I've seen that. I think last time I checked you had to submit your stuff to let MS decide if it'll be part of a non-existent future "app store" thing. At least for Office365 hosted instances?
