Have you tried copy/pasting from teams to another application, or especially code snippets? If you're lucky you can copy what you highlight, otherwise you copy the entire text of the current message with timestamp and all.

Code snippets are a pain to get right. The tilde key is the shortcut to get monospace fonts or code blocks, and it feels like I roll the die everytime I try to convert text to a code block.

Teleconferencing is also a major pain, where devices are not remembered for some reason. It's mostly ok, but every now and then it forgets my mic. This might have been fixed recently since it doesn't happen as often but it still happens.

Not to mention the hangs that comes up when switching between conversations.
