I have given access to users with the role of editor to use Bricks Builder and when they use the template element they cannot see the inserted template in the editor but when you visit the page you can see it on the front end. I have noticed this behaviour even when granting “full access” to Bricks for the editor role.
Please let us know if you are still experiencing issues.
As with any pre-stable release, please do not use it on a production/live website. It is only meant for testing in a local or staging environment. The more feedback we get, the better
