- You have set up teams inside your organization.
- You add a new app to the organization plan.
- Once the app was added the team can see it, but not all of them are included, so you have to go to the team tab and add the team members there.
To solve the issue, you would need to setup a default team group, so they will be copied to the newly created app.
