Rarely, you may see an alert in the app like this:
We value your privacy and ours and so our iOS apps check for a secure connection between the app and our servers. You will see this message when a secure connection cannot be established.
This may occur on some WiFi networks where the provider is seeking to act as a "man in the middle" between your device and our server. This makes it possible for your traffic and data to be intercepted and so we check for this and prevent any communications from app to server in this circumstance.
If you believe you're seeing this warning in error, please write to us at email@example.com, and we'll be happy to help troubleshoot.
