Hello Chris,
Yesterday, I followed your advice and before going to the Apple store, I called to make an appointment for technical help. Luckily, an Apple technician was able to help me.
Apparently, my iPhone SE came with a pdf scanner app. It’s in the Notes app. Go figure! He walked me through the steps to scan a document with my phone and email it to another email account. My scan arrived promptly with no problem.
Apparently, my phone suddenly started having trouble working with the free pdf scanner app that I downloaded in 2020. Since the technician wasn’t familiar with Genius Scan and how to get it to function, he guided me to Notes.
Once again, thanks for all your help and guidance. In the end, you led me to the solution! 😊👍
