Asset Store Submission: Medium Image Template?

I downloaded the latest image templates (icon, small and big) but when I try to submit the Asset Tool tells me I’m missing a medium.png file (460 x 250). The Medium.png file is not mentioned in the Asset Store guide nor is it in any of the template files.

I can see a medium.png in the instructional video. It looks to be split down the middle with white on the left. Does anyone know where I can get the medium image template in PSD format?

i also stumbled over this confusion. maybe the asset store manager doesn’t know that there’s no medium.png needed anymore yet?
however i quickly made a medium.png out of my big.png (resize and crop). if it’s not used, fine. if it is used, i can update it later, in case it doesn’t fit.

Yeah, I made my own medium as well using the big and submitted it. I mentioned this issue in my note to the reviewer.

Thanks
