are Apps really available for all devices?
I bought "Numbers" Apps for my iPad and now I have a new iMac but the Apps didn't install? I thought when you bought an App that is on one device it would be available on all other devices? The App store is now wanting me to pay for the Apps again? Is this right? Do I have to buy another version of these Apps for the iMac?
