Sign in again?? – Macworld Digital Magazine U.S. Review

It's bad enough that you have two avenues to view your Macworld subscription: Macworld and Zinio. Both should work I guess. Why does this app keep asking me to "subscribe" or to "sign in" when I AM SIGNED IN and I DO HAVE A SUBSCRIPTION? I don't usually use all caps, but when I do I mean it. Please fix this. Ask me to subscribe, or rather, renew my subscription when it's time to do so thank you very much.
