I received an on-screen "suggestion" to add memory to my Roku 3. I ordered and received a 4G microSD. I powered down and installed it. Opening screen says memory card detected, format or (preselected) quit. The remote doesn't allow me to select format ... or do anything. I powered up without the card, and the remote still worked well. I powered down, removed and reinstalled the card, reconnected ... same thing. Why did my remote not work with the card installed?
I've not connected the card to my PC to verify health.
What's the next step?
