I am currently using the PolarPro Tripod mount and I realised that the tripod screw at the bottom is blocked when I am using the mic adaptor. Im wonder if I am able to plug the mic adapter into the Unversal Mount using a C female to C  female adapter. Else, is there any solutions where I can make space at the bottom so the mic adapter doesnt block the tripod mount? Thanks for the help.

For now I don't think there is any way to get the audio adapter work using the universal port.
You can use a USB C male to female extension to get connected to the audio adapter. I think it will work, albeit unsightly.

Hi, thanks for the inquiry. We're sorry that this process hasn't been tested by our engineers, therefore, we couldn't guarantee if this would work, however, we're hoping that you could get the best recommendation that you may need from our valued DJI Forum members who manage to do the same scenario. Thank you for continued support.

I use this, it works well:

Amazon-  SMALLRIG Mini 15mm Rod Adapter to 1/4’’ Screw Mount for Monitor and Camera Cages – 1654

you can get a small type c extension cable to get around this.
