Hi, I have the family premium on my phone and I am trying to add my parents to it however it won't work. I have logged out of my account and their 'free' account. I have sent the invite, but when I click on the invite, it takes me to the log in page which I put my parents 'free' account info in and then it just logs them back in to the free account. There is nothing to ask about accepting the invite or adding an address or anything.
p.s. We all have Iphones
