What’s New

Version 21.06.20

Bug fixes
• Fixed: Tapping on an empty input field used to show the options for “cut” and “copy,” but there was nothing to select. What do you copy when there is no text? If you copy text that isn't there, does it even exist?
• Fixed: When editing a channel’s topic, changes were being saved even if you tapped “cancel,” essentially telling the app, “Yes, absolutely do that right now” instead of “Undo.” This bug has now been undone.
• Fixed: Beginning a message with a “slash” would cause the shortcuts menu to open, which then had to be dismissed before you could return to composing your message. Shortcuts are for saving time, not adding to it, so our inadvertent “longcut” has been whittled down.
• Fixed: Sometimes your workspace would indicate “-1” new users had joined, which was pretty spooky. While our terms of service do not have a specific clause against nonexistent individuals using Slack, we have made the executive decision to limit all workspace members to those denoted by positive integers.

Great great app

It’s a great 5 and definitely helps at work when everyone works remotely and stay connected is key. The only thing I still struggle is how slowly pictures load!! In the world where we use screenshoot snd pictures to support messages having to wait serval seconds for a pic to load (opposite to a few seconds on other apps), makes it really annoying. Another thing which is also irritating is “unsent messages” only been notified after several minutes. If you haven’t got a good connection, at times slack makes you believe that the message is sent. Only to realise that this isn’t correct a few minutes( not really few), later!

A real struggle to use

Slack used to be good. I won’t say great; it is a difficult job trying to give everyone the communication tools they want with a UX that is simple an quick. But the previous version of the Slack mobile app did a good job. The latest version doesn’t. I’m not averse to change, but having spent some time with the redesigned app the only thing on my mind is how frustrated I am trying to use it. Mostly because, after a few weeks, I have realised what I thought was my failure to grasp all this swiping back and forth you now have to do is actually a bug. The Jump to page or home page whatever it is, keeps disappearing. And I can’t get it back without restarting the app. Now I’ve realised restarting the app fixes it I feel less apprehensive about using it but it’s a serious defect that needs fixing. Other than that, the new interface still has me feeling lost and unsure as to what I’m looking at half the time. It doesn’t feel like an improvement. It was certainly waaaay too much change in one go.

I find the app constantly half a second too slow for my liking. This has the cumulative effect of making me slightly more frustrated over time as I'm using the app.

Slowness most noticeable with the delay in (or simply broken) notifications. When I see a red notification icon on the app logo, I find the fastest way to check the new update is to hard close the app and re-open, as this prompts the notifications to actually pick up the new message. It's also not a 100% success rate - sometimes I need to do this several times before the update is picked up. This has frustrated me when I've actually been reading the thread at the time, I know someone has added a comment, but it won't show up on my screen, even with a drag-refresh.

Slowness also noticeable when changing channels, navigating to threads and switching workspaces.
