Ok, I launched my first ads campaign for myself using Dynamic. That is totally new for me so I have questions. I'm only on day 3 but I've seen horizontal ads being used on insta which isn't ideal IMO. When you upload images (at first I had 3) should you do square and horizontal versions of each one. According to FB horizontal is ideal but I know that isn't the case for insta. How do you decide which images to upload for dynamic ads, how many, etc? Thank you for this amazing free help!
