The page for adding/editing user pins works OK from both the LCD UI and the web interface. But there is no way to DELETE a code at all! So I manually deleted the offending code from the lock itself, and it is still showing up with the old code on the A+ (probably the lock did not notify the A+ of the change -- maybe there should be a "refresh lock data" option?) I tried several things (empty string, "unassigned") but couldn't get anything to work
There really should be an option for this!
