MapQuest has not updated my street (the GPS spot is on my location but my PO address is placed down the street.
On my iPad it does not use the full (12") screen (even in 2X view) and does not provide a keyboard for data entry in some pages (e.g., Feedback) and does not allow cancellation of some entries.
I have only started to try to use this update so there may be more problems.
