It is saving to the internal drive. Checked the card with the Pro and it still works. Also getting some strange messages and loss of range. Am I a victim of the firmware update? Why aren't these updates vetted better before rolling them out?

Nevermind. I'm dumb. Much thanks to you tuber  IrixGuy's Adventure Channel. His video DJI Mavic Air - How to switch from internal to microSD solved the issue in 60 seconds.

Glad to know that you'd worked it out. Any further questions, please feel free to let us know, we are glad to help.
