iPad blocked by scam
Suddenly, on my sister’s iPad a message appeared stating that it has been blocked because of illegal activity and asking my to call an "Apple" telephone number. I’m quite certain it’s a scam - how can I get out of it? Can’t turn off the iPad, or do anything else, the message + blockage won’t go away. I’m using my MacBook Air trying to assist her.
