After 20+ tries it didn’t work

Went through way too many tries only to get” image is blurry, clean your camera, except the app kept losing focus every time so it wasn’t my camera. Made it past that problem eventually and got to the tilting stage. Every time for over 20 tries it couldn’t read my prescription and wanted to know if I wanted help (contact support) but I don’t know what support could do to help through email or try again. After 30 tries, my fingers are in pain and I’ve deleted the app. Not worth keeping when the app fails so often.
