We've opened a lot of tickets about the " useful activity badges" but they seem to think it's a feature, not a bug. (I assume to keep remote devs happy so managers can't drill down to the minute of time.) I know for sure that their underlying tool fo determine away time is very accurate.
Because it's an Electron app, i.e. another copy of Chrome.
Actually for all the money they've raised I can't understand why the Slack apps are so terrible. I use Mac and iOS versions, and they still can't show useful activity badges; video doesn't work on ios...what are the spending their billions on?
