When trying to update my mainnet Full Node’s QuickConnect from Photos App, I get this error message “That’s not a compatible QR code”.

Error message as stands gives no clue how to fix. In general, all error messages should give more clues as why it happened and what to do to fix.

I presume this time may be because 0.2.2 isn’t a mainnet release? If that is the case it should say so. If some other error, it should say what that error is. If an unidentifiable QR it should show QR text that was received and the opportunity to copy that bad QR to clipboard, and ideally where to go to get advice.
