I've had it, it's related to heat. You can get video feed and no telemetry ande vice versa.
The solution: Unscrew both vtx and goggles and replace the thermal paste to a new better paste. Also make sure you cool the goggles enough (don stan im direct sunlight ) and take off as soon as you can so tha the vtx doesn't get hot
Let's take flight together and elevate the world of FPV drones to new heights.
