I'm still wrestling with this, i am now convinced that what i wrote in my previous post does not work. In fact, I just Uninstaller and deleted everything, then reinstalled GL app, then movedelete app from internal storage to external storage card, then, logged into GLOBAL, then looked for settings to find a setting to indicate download all app media to external card. This is a problem, cause I could not find any setting to direct downloaded media to either internal or external storage. So, I assumed maybe it will download data to external storage since that's where GL app is located. I downloaded all things I wanted. Result, internal storage lost 2GB of space. No! My conclusion is none of my efforts solved the problem of GL app consuming precious internal storage space. Yes the app is on external, but so far, I still cannot find way to make data, videos, lessons, etc download to external storage. Frustrating. I think there's a software shortcoming.
