Hi. The internal storage and SD card on the GO controller both read N/A so I can’t take pics or videos. Can anyone help?

You don't mention which drone you have but your Avatar shows a Mavic 2 Pro. The recommended SD card for that is : Mavic 2 Pro. Sandisk Extreme Plus V30 A1.  I use a 64Gb Sandisk ULTRA card in my M2Zoom and I get a message "card too slow" - but it doesn't seem to matter as everything records just fine. You can use up to a 128Gb card I believe.

Do you know why Internal Storage shows N/A?
