    Hi Tran - 

    Uninstall, then reinstall the Slack app under Admin > Apps > Manage. If you find that updates are still not pushing to Slack, submit a ticket to for further investigation.

    Are you serious with this solution?

    I have a dozen slack channel integrations setup. Will I have to recreate all of those if I do this?

    Hello Tran and Mike, 


    This is indeed a generic solution and, if we want to see what exactly happened we would need to look into specific errors of these failures. 

    Since this will require more account specific troubleshooting. I'll send you both a proactive ticket to get to specific errors you might see on your end. 

    This is why we are asking you to contact us at if you are facing some issues, we would need to know what the exact error is to be able to determine what is happening. 

    Talk to you soon.
