I answer and explain what graphics should be placed to be correct.
In the icon field, we put our own graphics with an aspect ratio of 512x512 on a transparent background, without added shadows. PNG or JPG / JPEG format. May be in the watch icon.
My example (correctly goes to the store):
In the graphics field, to be used in other parts of the google store or their applications. Custom graphics in 500x1024. I also post here without shadows, but on my own background.
My example (correctly goes to the store):
Graphics / screenshots section for Wear OS. The so-called 1: 1 graphics, with me the aspect ratio of 450x450. Screenshots taken on the watch, placed in a square with a white background. A minimum of 4, of which the first 2 must be a perfect reflection of the face placed in the store. I do one for each display version: normally 24H and 12H and AOD 24H and 12H.
