I've been having trouble getting my DJI Air Unit 3 to show the Betaflight OSD, but I realized that I don't have any MSP connection at all because, when I arm the drone, the low power mode doesn't turn off. Today, I reflashed the latest version of Betaflight and used the "OSD for fpv.wtf, DJI O3, Avatar HD" preset. I've double-checked the wiring harness for the air unit to the flight controller (FC) to make sure it works, and that I used the correct UART. I have no clue what else to do—I've tried soldering it directly to the FC instead of using the connector and a series of other things I can't remember. I would really appreciate any help with this, as I have no idea what to do next. FC, air unit and goggles v2 are all on latest firmware.
EDIT FIXED kinda:
went back to betaflight 4.3 and it worked fine. i couldn't get it to work on any later version. i have no idea why but just swiched to inav 7 and it also works fine.
