When you're part of a team, you can have access to both - a team and a personal account. The personal account is only accessible to you. The Team account, however, is accessible to all team members, where, depending on their role, they can view, edit and publish. Moving or copying projects between accounts allows controlling who has access rights. You can move or copy projects:
To copy or move projects one by one:
❶ Hover over a project thumbnail in the Library and click the three dots "...".
❷ Click Move to, and scroll down the list and choose the account where you wish to move the project.
❸ Choose to Move or Copy.
The option Move will move the project to the chosen account.
The option Copy will create a copy (with a new ID) of the existing project into the chosen account. The original will remain in the initial account.
