Every Project must be assigned to a Team for users to have appropriate access to the Project.  To verify Team assignment(s) or make/edit assignment(s), in the Navigation area, click Teams >> Team Assignment.

You may filter the page using the Select Filters dropdown slider menu at the top to quickly find the Customer and Project of interest.

Use the dropdown in the right column to assign the Customer-Project to the appropriate Team and then click Apply Changes in the bottom right of the page.
