Tried to open the app this morning - I have version 2.1.1 and got an error "The version of this application is no longer supported". I have an iPhone 4 running iOS 7.0.3. Suspect the issue might be the upgrade to 7.0.3, because the app was working fine before I applied that upgrade, and I think this is the first time I've tried to use it since.
Is anyone else having the same issue? I tried to report the problem via the app support page at Vodafone.co.nz, and got a "method not allowed" error from the website.
