Q: Cannot access iTunes App Store with iCloud ID

Hello,

I have two different Apple ID I use respectively with iCloud services and iTunes/App Store. However, in the past I used the iCloud Apple ID to access and download some apps from App Store in my iPhone 6s.

I recently changed the password of my iCloud Apple ID and from that moment I cannot use it to access the App Store to update the apps.

I can access iCloud but not the iTunes Store App Store with it.

How can I solve the problem?

Hope I was clear.

Ciao

Marco
