Proxy keeps reverting to None
When entering our proxy server, it reverts to None after saving changes. This works on our older iOS devices but not on our 6th gen ipad with iOS 13.5. It doesn't matter whether I use the DNS name or the IP address. Again, either works on other devices.
I upgraded from iOS 13.4 to 13.5 and consequently rebooted. No change.
The proxy address is entered manually. We don't use PAC.
