What the top complaint sounds like
Slack: confusing ui & ux
★ Terrible UI …account. Another set of hoops I have to jump through when Slack automatically signs me out. Logging back in through google’s interface doesn’t get you into your slack account under the same Google email either, so you have to log in through slack’s interface into that same email v26.09.20 · 2026-09-13
Zoom: login & account
★ Worst mobile experience …to reach out for assistance on how to use this god awful app they require you to upgrade your membership to a business account just to get a person on the other end to help you navigate the app. Overall don’t support this trash. v7.1.0 · 2026-06-26
