I have been getting errors in visual studio building to UWP. I noticed that in Unity, under the UWP, under the store logo, there are 3 icon sizes that are listed (70x70, 90x90 and 120x120) that are not in visual studio. I tried looking these up on microsoft's site that lists the icon sizes and did not see them. So why does unity include them? is this some legacy issue? Also, can't unity just name these in the unity editor the same names as they are in visual studio?
