I have about 40 apps that need to be updated, mostly iOS but also some OS X. Some are free and some are ones I bought previously. I have only ever had one apple account and am still using it, but when I try to update any app I get e following error "You can not update this software since you have not owned the major version of this software". I can however download new apps. My account is based in Canada, I am currently in Australia on holidays for 5 weeks.
How can I update the apps while I'm here?
