Hello,

Using 50mbps mode other goggles couldn't spectate, is this expected or something is wrong ?

Yea I noticed this today when trying to get audience mode working with a friends new set of goggles, I switched back to 25mw and it still didn't work.
Both goggles & air unit on the latest firmware. Does audience mode not work anymore?

OP, did you try & get it working on 25mw?

It works on 25 mbps, just reset goggles (all of them) after updating, there is menu option for that, called something similar.

Also, strangely, now spectating goggles is showing custom OSD
