IOS 8.3 clashes
Several of. my colleagues and I are dealing with network and protocol errors when using apps through the Tunnel VPN after upgrading to iOS 8.3. The problems stop when we are not using the VPN. No major issues with tunnel outside of that though, but it's a big deal at the hospital where we work.
