#msteams
I am not a friend of #Microsoft #Teams, but I like that I can now chat with the official company tool with people of other companies, so I can actually directly contact someone from our biggest competitor for this project where we have some interface between our systems and ask things directly by #MSTeams. This will probably reduce the use of #WhatsApp a lot. Not that I used #WhatsApp for it, but I imagine that this was the go to tool for a long time.
