The easiest way to remove the “Go Back” link from the single entry view of any GravityView is to enter a single space into the Back Link Label setting field under the view’s settings.

I tried to find an appropriate hook for more than a handful of minutes and failed. If it’s stupid and it works, it’s not stupid.

Why

The “Go Back” link appears by default on all GravityViews, and leads to the multi-entry display of the view. If there will never be multiple entries available to display a user, it makes sense to lead the user directly to the single entry and disable the link.
