My trips are automatically sharing with a team member. Is there a way to turn this off?

If you're part of an agency, new trips you create are automatically shared with your Agency Owner/Administrators. However, you can remove agency access to a specific trip if needed. Go to the Overview tab and look for the 'Collaboration' section. You'll see an 'Agency' section where you can remove agency access by clicking the 'X' next to your Agency Admins' Access.
