I have no idea if I'm in the right place on these boards, but it seems like this is better than trying to contact support (no live chat appears to be available). I just purchased coverage for '3 devices.' My Mac is fine, but I'd like to install it on my IPAD as well as my Samsung phone. On my IPAD, I downloaded the app but it keeps asking for an invitation code. I put in my key, but that isn't working. Can anyone tell me how on earth to do this or where to find instructions to do so? I'm ignoring the phone for now. I thought it would be far more simple to install on the IPAD and am disappointed and irriated.
