I'm trying download an app but it says: UPDATE UNAVAILABLE WITH THIS APPLE ID. THIS UPDATE IS NOT AVAILABLE FOR THIS APPLE ID EITHER BECAUSE IT WAS BOUGHT BY A DIFFERENT USER OR THE ITEM WAS REFUNDED OR CANCELLED. Whats the problem? I cannot neither download nor update apps like viber, tuneup radio, aliexpress, and many other free apps. PLEASE let me know what to do.
