I'm just impressed how bad slack is on mobile. Either I'm getting messages on my computer and phone (on phone after I've responded on the computer) or not at all.
I've been having this problem with push notifications for quite a few apps, but Slack just seems to genuinely do whatever the hell it wants, regardless of whatever I've set preferences to.
Yeah I know what you mean. Like sometimes I'll get messages hours after they are sent. Even when my main computer is off so would be considered "away". Now I just have to frequently check slack and that in itself feels like a dark pattern.
