It used to work very well. I hadn’t used it in a while and I tried to use it today and every time I touched the screen to highlight a word it would shut down and boot me out to my iPhone Home Screen. I even deleted the app and re-added it but I got the same result. Now it’s deleted for good. Very disappointing. However, I will download a different word search app and try playing the new app once I find one I like. I have an IPhone 11 with the latest software upgrade. So I don’t get why it won’t work.
