I now have a "suggestion" in Security and Privacy, saying that Google Play Services requires an update. When I tap "update", I get same old message that it is up to date! Obviously, if the phone thinks there is a Security/Privacy issue here then it should be fixed or, at least, addressed urgently? As someone has already commented, for an expensive flagship to be left vulnerable in this way is nothing short of scandalous and I'm also sure that, as much as it pains me to say it, I somewhat doubt that Apple would allow this to continue?
