Being a newbie to tech stuff, the app was a little daunting (LOL) to me, A bit clunky and non intuitive...HOWEVER to anyone with any Computer skill, it would be simple. The support I received from the Widgetic team was well beyond anything I have ever come across and they were very professional as well as patient. This is the way you imagine every company would work in a perfect world.
Peter, it looks like the app works great on your site: https://www.pastcolours.com.au/collections/photo-restoration-touch-ups-price-guide.
Remember - deleting items from the Editor removes them from the app as well. Stay safe out there!
