What is it with @SlackHQ’s unread marks these days? This is driving me crazy

Whats going on here? 👀 Do you mind sharing some additional context so we can help get to the bottom of this?

It seems to take an extra one or two seconds before things are marked as read, which leads to me having to reopen every channel again

Hmm ! Is this on desktop or mobile? If it's on desktop, is it in the app or a web browser?

Mobile iOS app

Thanks for that. What version are you running? To check, open Slack and tap You > Preferences. The version details are at the very end of the menu. Do you experience this over mobile/cellular connections, or wifi, or both?

22.05.10 (423751), both.

Thank you for getting back to us, and letting us know your app is up to date. To troubleshoot further are you able to provide your iOS mobile app logs via email at feedback@slack.com?
