I have followed Slack's instructions to clear unread messages and still "Threads" is bold in my Slack app. It is not bold on my desktop app.

Slack's instructions:

Mark everything as read on desktop

  • From the Slack desktop app, open the affected workspace.
  • Press Shift + Esc.

Clear the Slack app cache

  • Tap "You" at the bottom of your screen.
  • Tap Preferences.
  • Tap Advanced.
  • Tap Reset Cache.

Clear app data from your device settings In addition to clearing the Slack app cache, you can also clear the app data from your device.

  • Open Settings on your device.
  • Scroll down to Slack in the list of apps.
  • Tap the toggle next to Reset Cache on Next Launch.
  • Open the app to reset the cache. Note: This will log you out of all workspaces you're signed in to.

This third step did NOT log me out of my workspaces FWIW.

  • Try quitting and reopening the app after the 3rd step
