Logging of my account doesn't exist or is completely hidden. Logged on with the wrong account, now it takes me forever to find a log off. That is the first thing an app developer has to do, create basic login logout functionality. How can you miss that! Worst app I encountered this year.

I use Slack on my desktop (browser) and the mobile app, and it's very frustrating that notifications aren't in sync anymore. My phone still shows notifications that I read hours ago in the browser. I know that this affects our entire team (not sure about iOS). Please fix this, this used to work in the past. I had mixed feelings about the new UI, but I'm actually fine with it now. (Though not sure if it's a good idea to have a non-standard navigation for the average user...)

While speaking (huddle or call), Slack does not use the Bluetooth headphones automatically. Also, I'm missing a toggle speakers on/off button. It's cumbersome when all I want is a spontaneous call. Worst thing: A colleague wanted to share their screen and I couldn't see it. Skype and other chat programs manage to do that on a mobile device. Four stars if you get that working - seriously, it's a basic functionality even for cell phones. Five stars, if the software stops being cumbersome.
