I have an IPhone 5 and, for a couple years, I've been content with whatever version of Ios 7 I had on it. But when I needed to add the Alexa app, I upgraded to 9.3.3. Since then, when someone sends me a text, it also goes to my wife's Ipad and She's not real happy about that. I'd appreciate suggestions on where to look or what settings to change to fix it. I do use her I-store account but otherwise, we're different. Thanks.
