Hi Odar,
There are couple of reasons for this -
- The new invitee is already part of the project. If this is not the case, please move to step 2.
- Please check if the license mapped in the project is your Business license . You can check this by navigating to Settings > Project Details > Project license (screenshot below) . If the license is personal license (free license) , please update the license to the Business license and "Save" the changes in Project details.

If you continue to face challenges after these steps, please share your userID and project details with our Support team (connect-support@trimble.com) , so that they can help you out.
Regards
