Like @LLGE I have found myself on 200731 before discovering that there is no longer an ADB option available to install apps 
I had avoided doing a firmware update myself because when I checked with Hyundai, they said it could invalidate my warranty if anything went wrong, so I played safe.
If only I had discovered IoniqForum before I allowed my dealer to do an update, I'd be in a better place. Oh well!
What's the easiest way to keep an eye out for a solution to this please, other than checking back and searching through every so often?
