hola To avoid the constant nagging message to upgrade I had a tvOS profile installed on two different iPhones running iOS 10.3.2. Now on both phones the upgrade messages showed up again after a couple of month. After wondering what happend I recognized that both tvOS profiles disappeared. So I deleted again the IOS 11 download and installed a new TvOS 11 profile. Did it happen to you that it uninstalles? I checked now the Apple certificate which is valid till may 2019. So can I hope that it will stay like that for that time?
