icloud approval request
I keep getting notifications on my IPhone & Ipad saying ' approval request' to continue using iCloud, sign on this device, sign into iCloud on another device or enter your security code ! I have tried to find out how to do either of these things on other devices but it's not clear what I'm supposed to do !? I've disabled 2 factor authentication because that was causing problems ! Any ideas what I can do ?
