I want to love it…

It seems like slack is trying to do too many things, but the real problem that I find is the interface is somewhat disjointed.For example the left hand list of channels conversations etc. it’s sort of annoying to manage. Previous conversations with other members or groups of members seem to stay listed in the left hand pane with no easy way to clean them up. it would be nice if we can set a time limit after which those historical conversations can at least be archived or moved to a different list that is not normally visible. When I want to send a message to a particular individual or small group, I have to use the ad button at the top of the screen multiple times to select those people. It would seem more convenient to me to have that member list be an expandable list on the left-hand side and I simply need to select or check off the members who I intend to send a message to. So basically I think the functionality is great, but the organization and layout of the application itself just seems clunky. Even the appearance and spacing of messages and replies isn’t usually segregated enough.

Slack for iPhone

Does NOT update dynamically. Badge shows unread messages when there are none. I waste a lot of time checking for messages that have already been read on my computer. Not useless, but not good software!

Where the heck did dark mode go?

Used to be able to make the app run in dark mode and now its gone! Bring it back

Lots of problems
Prophet Clyde Lewis

This app has a lot of problems the desktop is fine but the app is horrible


Lot of 🐛 bugs. as you open the app, It always shows you updates with bold text that there are some notifications but eventually fades out. Some data refresh issue upon app launch. Fix it!

Profile Edit

When editing the phone number in your profile via the iOS app, there is no formatting nor a way to add “-“ to format it yourself.

Issues with slack app

10/16/2020 I have multiple workspaces and on my iPad, one of them have dot next to it’s name, indicating that I have a new slack, but there is none. “You’re up to date” your app informs me on each channel. “No new replies” each thread displays. Did reset app’s cache, did reboot of my iPad. Did delete and reinstall your app. The dot is still there. It’s reappearing issue, comes back once in a while. Can you please fix it once and for all. It’s very distracting, when you get many business related slack and never know if that dot there due to your bug, or if I really have a new slack. 05/11/2020 Do not see any changes you described in update to 20.05.10. Not on iPad not on iPhone. All design looks exactly the same as before the update. Both devices running latest iOS. 02/15/2020 On iPad and iPhone, workspace keep showing white dot in the upper right corner of the workspace logo/icon indicating that there is unread messages, but there is none. “You’re up to date” your app informs me on each channel. “No new replies” each thread displays. Did reset app’s cache, did reboot both devices. Did delete and reinstall your app. The dot is still there. Please fix.
