Usb storage help

Can anyone help me my Amazon 4k FireStick problem, after following Troy’s 33 minute video twice, I still cabt move apps over, I have checked for typos with a fine tooth comb but keeps saying failed, also the USB storage is not showing on the main page, tried one last time with rdb bug, but it’s kicking me out, any ideas please. Jimmy. Tank you

@jimmy.royle you probably noticed that I stopped responding to help questions on that page due to the fact that it is an in-depth tutorial and impossible for me to troubleshoot. I am personally waiting for the new UI update on my 4K Stick as we can then expand storage without all of the BS commands.
