Can't access USB thumbdrive

I’m trying to use a thumb drive to copy across the new Amazon Prime apk, but cannot find any option in file manager to access USB storage. I’ve tried this with a few different drives, but none of them seem to detect.

I followed the advice in the guide here ( How to copy files to internal storage – Philips Projection ) but the options it refers to don’t exist for me.

Any advice?

You can also find the Amazon Prime apk in the Aptoide TV store on your Picopix Max.

When in Aptoide TV, type in the search box Prime Video
and you’ll find Prime Video - Android TV v5.2.45

Press install and you’re good to go.

What format is your usb drive?
