I have Slack (Mac app) set to scroll to oldest unread message and mark the channel read, but instead it scrolls to the newest content. Is that a bug, or am I hitting the 10K line thing?
Seems inconsistent, though. Right now, I've gone to several channels with unread msgs and it's done the right thing; but when I came back to the app after my laptop had been sleeping for hours, it scrolled to new stuff.
I think I was on #C03S1KBA2 at that time
@echristopherson: I see the same weirdness in the browser version in Chrome on Windows 10.
