We can create a team easily. But my friends cannot join to my team, also I cant join to their team.
I’m sorry that the Team invites are malfunctioning! This is a known bug that we are working to fix. I will give you an update once it is working again!
In the meantime, you should be able to invite users to individual projects.
Team Invites has been fixed. If it still does not work for you, let us know!
