I have had my premium membership since November of 2010. I bought the iPhone app about a year ago. I have been using the app, along with my gps, for the past year or so. Today, out of the blue, my app shows I am a "basic member" and none of the premium caches are showing up. I contacted Apple, they suggested I delete and re-install the app. I did that, nothing changed. I did a reboot on my phone, nothing changed. I signed out and signed back in, nothing changed. My membership is paid up. I am premium online, but not with my app. I am confused. Don't know what else to do. Any suggestions?
