The photo is when you open an listing below the first large photo. The first image of the two little pictures is a picture and the second is a video. On the laptop it is also displayed, but on the Iphone and IPad it is not displayed. It’s there but you don’t see it. On android you can see it like in the picture.
Thank you for your response but I do not think that it will solve this problem because I do not change something in the backend or something like that. Maybe I know a solution and I will create a new entry.
