I'm a little confused because I had a designer make sets of display ads for me based on Google's most engaged sizes (336x280, 320x50, 300x600, 728x90, 300x250) and I also had them make a square logo as well. I went into responsive display and uploaded these assets (along with a lot of other sizes as we were working off of old templates before this) and ads told me I needed to include a square and a landscape image. I selected some images to represent those sizes, but it still didn't accept I had chosen a logo and a landscape, so I had to scan my website and now it's just reusing old images that aren't the banners I distinctly made for display ads. Am I missing something here? User error?
