As it says. I havent used Getflix on my iPad Pro, ever, but on the older Air2 I never had any issues. iOS is simply refusing to allow me to have anything but Automatic DNS (and yes, I do try to save, but it immediately reverts to Auto and the router DNS).
Its still working on the AIR2 which I had not updated to 12.2, but am now doing so, so will see if the Getflix DNS persists or if iOS reverts it to 192 etc
Any clues, anybody?
