Their video is downright buggy. Some users just can't share their screen with me while others can. I've tried "resetting" the video by disabling incoming video and then reallowing it, but that just freezes the video. Audio is frequently bad too when people speak alternatingly. The new speaker has 2-3 seconds of muffled audio until they're clear again. Especially annoying when speakers rapidly change and all you get is semi muffled audio all the way. Also the inability to respond to a specific message on desktop has baffled me. It seems like a basic functionality in chat software these days but teams only decided to give it to mobile? Just... Why? And many emoticons have been renamed or simply removed. Why reinvent the wheel ?
