Possible Slack iOS bug: I have a couple names in my list of DMs that I cannot seem to mark as read. I tried, just now, looking at them on the browser and hitting Esc, and that didn’t help. Even doing the Shift-Esc “mark EVERYTHING read” didn’t help. There are no messages in there, so I have nothing to long-press on to get a menu. They show up in the app as having 1 unread, even though there’s no content. I suspect what happened is that there was one unread message that I read in an email notification, and never read in the app or browser before it got purged from the history b/c my team is using the free service. It’s mildly annoying that I always see a flag on the app for at least 2 notifs, when there really aren’t any new messages.
