Apple ID sister
Hello,
A few years ago I used the Apple ID from my sister to download some apps.
Later i create one by myself. At this moment when i click at (for example) Whats App
i need to fill in the password of my sister. But i want to do it on my own ID.
Some apps are on my own and some are on my sisters account.
In my settings I only see my account and not the account of my sister.
How can I put everything on my account?
Greetings,
Vicky
