An admin seems to have redirected a dead slack channel to its replacement.
When I am using Slack via a web browser and I click on the channel, it is redirected so I cannot sign out of it and I cannot find where to remove the channel from the "Workspace switcher"
I only have this on the WebSlack; the macOS app does not have this issue since I only see the channels I actively have signed into since I updated the app.
How to remove the dead channel from the Web View?
