"I can view the project, but I can't add photos or perform other operations."

Although you can view the project, if you are unable to perform actions such as adding photos, it may be because you have not been added as a member for the project. Please ask the project creator or project admin to add you as a member.

Note: For internal projects, you can add yourself to the project. For instructions on how to add members to a project, please refer to this guide.

If you are a company administrator, you can view all projects involving your company members. However, to perform actions on a project, you need to be added as a member.
