Just wondering now that I have a memory stick attached to firestick, and I have most everything download to memory stick, my memory is still only about a gig on firestick?
Your USB stick is not showing up there. It should if its connected properly. You should also see it with apps like x-plore as well. They can and do disconnect in which case the app won’t even show up.
I’ve reloaded apps and they show up like this on memory, so it looks like they are loading on memory stick.
I would also turn off the auto offload feature. Make the choice for yourself. Don’t forget not all apps will install on the USB unless that option is coded into the APK install by the dev. Also not all data of the app will be kept on the external USB, some will still be on the internal memory.
