Hi there. Anyone having issues with iOS 11 personal hotspot? I can't seem to link my iPhone 7 Plus (iOS 11 PB4) and iPad Air 2 (iOS 11 PB4) consistently for personal hotspot using WiFi. I can pair them via Bluetooth, but it doesn't seem to work properly. Netflix downloads time out, and surfing doesn't work on the iPad. I'm wondering if anyone else has this problem.
