Slack Icon update, thumbsdown!

I don’t mind the logo, but I am disappointed in the newest update to make the icon background white. Should at the very list provide the option to chose the background color icon in the app.

Another issue I have been experiencing with slack on iOS is with notifications. Often times, but not always, it will make the notification sound and show the notification on the lock screen for just a moment before it disappears. So unless my phone is next to me, I would not know there was a notification that went off. When you use slack to receive alerts for oncall, this is very bad.

Should also implement a dark mode for the app itself.

Great platform with a minor issue

I’ve been using slack for a year now with work, classes, and organizations. It has a really nice setup and I enjoy the fast communication. But something that I think could be changed is the do not disturb - I think there should not be a default automatically turned on and people should instead receive a suggestion to change this themselves in settings, many people don’t pay attention to this and I have a lot of messages that end up not being seen. The big thing is that after the do not disturb period ends, you don’t get notified of the messages that you received within that time period. So many people end up not seeing those messages until much later, or not at all. I think slack should notify you immediately after the do not disturb period ends so you can respond to those messages in a timely fashion. This seems like a big thing to overlook.

Slide into my DMs

Using slack is easy, it’s convenient and I recommend it. The ONE thing that I wish were different is the DMs. I’m in THREE separate workspaces with overlapping members in the group. Sending a DM to one person in one workspace means not seeing the private message thread when sending a DM to the SAME person in another workspace. We have a workspace for the village in which our Burning Man camp lives to communicate with the village leads. We have a camp message to chat amongst us as camp members. Some of us in that camp are involved in an art project that includes other people. There’s no good way to keep up the DMs with the people who also are in my same workspaces across all the workspace. As you can imagine, DMs are usually OT and all over. This is the one thing that could use a tweek, IMO.
