- Simplify navigation: 34 complaining reviews, avg severity 2.0/3. What to do: Run a quick usability test on the screens users mention; remove extra taps and pop-ups.
“I don’t love slack. In fact, I really can’t stand it. I think it’s hard to find particular messages and it’s not intuitive like other messaging platforms.

What to do: Check notification delivery and let users control frequency in settings.

What to do: Explain the change in-app, restore the most-missed option, or offer a setting for the old behaviour.

What to do: Read the quotes below for the exact request; consider a public roadmap.
“I really wish Slack would bring your pinned agents like you have on the desktop. readily available on the home screen in iOS. Also, what is up with prompt links not working on iOS? It’s been over a year” (3★, v26.10.11, US) - Justify or adjust the price: 8 complaining reviews, avg severity 2.2/3. What to do: Test a cheaper tier, annual discount or one-time purchase; show what paid users get.

How to read this
Apple's public feed only shows recent reviews, so this is a snapshot of the last weeks or months, not the app's full history. Popular apps attract complaints in proportion to their size; the useful part is which issues repeat. Generated 22 October 2026. We have no relationship with Slack Technologies, Inc..
