Other Apple ID and Backup using itunes
I wonder if once I used other Apple ID to download the app. After that I backup and restore my iPad to my computer using iTunes. I restored all the app except the one that was downloaded by other Apple ID because I need to sign in to other ID
I want to purchase the app by my Apple ID. I would like to know that after I purchased and installed the app, will the content in the app be restored (by iTunes)? Or I have to use the other Apple ID and password to download the app and restore content from my computer?
Thanks
