Forms - Why can't I send a Form/Action?

How to get permission to Send PDF records. 

Question: A saved form doesn’t give me the option to send, even after I get the PDF.

To be able to Send a Form, you must have Send permission for the Project.

Ensure the Project Owner or an Admin User (with Access All Projects) has added you as a Project Member with at least Send Records permission. 

Permission levels are cumulative, so you can achieve this by either having Send Records or Edit Project access.
