But they pushed out a new version recently. Now you've got Teams Classic and Teams NEW (work or school)... at least on the Mac.
It's sooo much better. Way more stable. Search is a delight (relatively speaking). We get far fewer complaints now.
Worth mentioning: We only use the "Chat" aspect, we don't use the "Teams" aspect. If we want to discuss a project, we just spin up a new chat with relevant parties and rename the channel to the project. Works great. We could never get "buy in" on the Teams aspect, nor threaded discussions. The main reasoning was having to monitor two tabs in the product. Everyone just wanted to stay on the Chat tab, so we made it work.
