This feature request is still in the works. No additional details to share at this time.
But the team is hard at work to ensure it is implemented in a fashion that will meet your expectations.
Can’t add files or folders from the app.
Can’t upload iPhone contacts.
Reply is not intuitive and starts a new conversation which is confusing. You can’t see what is in the original conversation unless you expand.
Notifications are not good and easily missed. Why would you make it default that if the desktop is open you don’t get notifications on the mobile?
Overall the Slack app is much better and easier to use.
Teams feels clunky and half baked.
