Anyone else facing issues with personal hotspot, on all three, USB, Bluetooth and Wifi? Am on an Airtel connection in India - on 10.13.6 and iOS 12 Beta 4. There is definitely a drop out, have done all the usual reset all settings, reset network settings etc. Connection lasts for a couple of minutes and then stops working on phone and MacBook Pro. have to then turn off the network (either through airplane mode or turn off data) and then starts working for a couple more minutes.
