Hello everyone. I have a website and I want to place a small horizontal banner in a specific location. I created an ad unit with a width of 320px and a height of 50px, based on a template I saw on another website for how I want it to look. In the mobile browser view (Chrome), the banner appears exactly the way I want it, small and discreet.But when I open my website through Instagram's internal browser, where my content is most consumed, that same banner appears in an extremely larger size, like a square occupying almost the entire screen. What did I do wrong? Why doesn't the same fixed banner ad size appear the same on Instagram? I appreciate anyone who can help me; I'm a bit of an amateur at this. l
