Hi... My problem is that I connected the air unit with the Mamba F722 dji Mini card.
Osd on, uart 2 msp on, I put some information on the osd screen and saved it. I cannot see osd information in the glasses. I tried other uart channels. I swapped the Tx and Rx cables. But there is no result. I had no problem with the F405 MK 2 I used.

Did you turn on custom OSD in the goggle settings menu?
