I have several pairs of polarised sunglasses (Ray-Ban, other brands) and the display of the Watch Pro 2 is not visible through them. Turning the watch or the sunglasses 90 degrees and it all works fine but obv that’s not convenient. Other watches and my phone are readable with my sunglasses just fine straight on (but not when turned 90 deg). Basically the watch glass needs to be attached rotated an angle of 90 deg from where it is now.
