Why is the “Approve build” button not visible?

This could be caused due to one of the reasons mentioned below:

1. Stale browser cache 
2. The current build is not in a state which can be approved, like failed build, etc.

The issue can be resolved by performing one of the following:

1. Do try to log out of the Percy dashboard, clear the browser cache, and login back
2. Try logging into Percy using incognito mode.

Performing one of the above, you should be able to view the “Approve build” button in your Percy build.
