What’s New

Version 19.11.20

What’s New
• The size of text is now controlled in the Accessibility settings of your iOS device rather than inside Slack. We used to have a separate preference for it inside the app, but it makes a lot more sense that you would want to have the same size text whatever you’re reading.

Bug Fixes
• Fixed: Attempting to reorder your workspaces would occasionally result in them ending up in a completely different order than the one you put them in. The order in which you put them? Either way, they no longer belie your reasonable commands, and will fall into line as requested, no longer out of order.

Fantastic and constantly gaining parity with desktop. Auto dark mode?

I spend a lot of time for work and beta testing apps in Slack. It’s nice to have access everywhere. Except when notifications constantly go off no iPhone+iPad+Mac LOL!

Love the new Dark Mode but why not allow auto switch on screen brightness that is becoming the norm now?

Slack for Apple Watch

So I’ve been using slack on my iPhone and Mac for about two year and I’m very happy with how it work! But I’ve had some problems on my new Apple Watch; when I get a notification it comes up with the option to dismiss or reply and if I hit the reply button it quits the app and then if I go on my iPhone it comes up with blank un-sent message. So I think the reply option is broken and needs some work. Also, there is no option to access channels from the Apple Watch, only DM’s and mentions. Channels being the main way people in my team communicate I would love the ability to access channels, not just single messages as they come in (which I then cannot look at again once I have either dismissed or attempted to reply to it)
Thank you for your nice iPhone/Mac message app, but I think the Apple Watch app needs a little work

Always great and always getting better!

Been using slack since the beta before it was released and have found it has had massive improvements in how we connect at work. So friendly, well considered, well designed and well built. I see slack as one of the benchmarks of how apps should be built. For people. Well done folks!
