First, double check that you are connecting to Photoshop without errors.
Then, make sure that you are loading plugins correctly. If the Eazl rendering plugin isn't loading, then eazl can't save work to Photoshop.
(most common cause of this is moving the application or plugins folder by accident)
The app will not save work on my ipad either. Any thoughts?
