Q: I'm signed into my apple account with my ID and I'm trying to download something but someone's email is popping up and it's not mines

Hello Ladychelss,

I recommend checking your settings to see if you are logged into the iTunes and App Stores with the Apple ID you would like to use.  If you need to change the ID, you can use these steps:

Changing your Apple ID account

Tap Settings > iTunes & App Stores, then tap the Apple ID signed in.

Sign out of the current Apple ID account and then sign in with another account or create a new Apple ID.
