If you have a Free, Starter, or Pro plan, you may encounter a limit when trying to create new projects. The limit notification will let you know that your account is over quota. To bypass this limit, you must upgrade your plan. For more information on what each plan offers, check out this article: Which plan is right for me?
Why am I seeing a limit on the Team plan?
Team plans allow for unlimited projects, but customers will sometimes unexpectedly encounter a limit. This often happens when the customer has both a personal plan and is a member of a Team plan.
Team members may encounter a project limit if they try to create a prototype or board on their personal account rather than the Team plan. To create a prototype or board on a Team plan, check out this article: How do I create a prototype on a Team plan?
If you create a prototype under the Team plan, you will notice that—rather than you owning the prototype in your personal account—the prototype belongs to the Team plan owner by default. This is to ensure that all members of the team can access the prototype via the Team account.
