I have just purchased a PIA VPN subscription and installed their app on my WiFi only iPad running iOS 9.2.1. Every time my iPad goes to sleep I lose my VPN connection. I contacted PIA support and they blamed it on Apple and say it's a feature of iOS. They said notifications and push emails etc will continue to come through on an unsecured connection. But that defeats the purpose surely? I'm frustrated that PIA's support articles or sales literature doesn't mention this anywhere. I found a thread on the Apple forums that says this is a problem that has been going on for years, Apple's implementation is designed to prevent battery drain. But digging around the internet and searching the forums here there is very little mention of it. I assume this would be a massively publicised problem so I'm wondering if what PIA told me is true, or is there an effective work around?
