[BUG] iOS client (0.0.20181104) sometimes kills WiFi connections/switches to LTE (John)

[mbox at reves.xyz]

I can confirm the same issue using an iPhone 8 Plus on iOS (12.1 build 16B92). I have seen it happens when the phone goes from wifi to cellular network and then it no longer connects to the VPN through wifi. I am using the following version:

iOS client version 0.0.20181104 (4)
Go Backend version 0.0.20181018
Connecting to the Mullvad wireguard VPN servers. 

I can also confirm that a reboot solves the problem. I have also noticed that when it goes from wifi to cellular the vpn connection seems to persist but the phone has actually no internet connectivity.

Best regards.
