I don't under stand why its so hard for square to give the measurements of the main banner. I have tried every possible combination of sizes and yet its always cut off and even some are blurry. when They look fine on the desktop they look terrible on mobile. When they look ok on mobile they are terrible on desktop. Can someone please tell me what the size of the main banner photo is suppose to be weather I use the image as a background of the image in the square placement holder......
