The install for Persistence goes OK and it is potentially a very useful add-on to Gravity Forms. The problem comes in Form Settings. The box labeled "Enable form persistence" will not stay checked after updating form settings. This is true even after also checking "Require user to be logged in" is checked and the "Require Login Message" box is filled out. I have tried this in both Chrome and Firefox. Many users on the forums have also had this same problem. There is very little documentation for this add-on and the developer, Astha, is either unable or unwilling to support it. Gravity Forms simply points you to the developer for support, which, after multiple attempts, has been nonexistent. A persistence plugin for Gravity Forms has great promise, but I wish Gravity Forms would put one out so it would work and be supported.
