Apps keeps asking for iCloud password
Hi, my iPhone keeps asking for password of the iCloud account the first time I open an app. After a restart or when the application updates or closes itself, it asks again for the password.
This has started the moment I changed my Apple ID password and I switched the main e-mail of my Apple ID (I have many emails registered in the same apple id account).
I had ****@outlook.com now I have switched the main mail to *****@icloud.com
I already updated the iPhone and logged out of the iCloud. In fact I did a full reset of the iPhone without using a backup, and I logged to my iCloud id with the 'new' credentials.
(So maybe iOS think the apps are 'purchased' with another account? In fact if I download ('purchase') a free app on the store, doesn't seem to ask the password when I open it. Are they stored in the plist file or something similar, and how to change it? )
