Nice new interface, but buggy in offline mode

I installed the new update, then launched the app. From the main menu I tapped on the SAS Survival link. It went through a setup screen, then opened the guide. I then closed the app and tried it while my phone was in airplane mode. I then receive an error message that the app needs to be connected to the Internet for the first time setup, and I cannot get the guide to open. This is concerning, please fix ASAP!
