I have a 2Mb, 27sec mp4 video which I’d like to display in the ad reel at the top of a plugin page. I can upload the video, I can play the video in the preview, I can choose what order the video comes in the carousel but when I hit save, the video is not presented in the carousel. I have tried different formats (mov, different encoders) to no luck.
Please can someone suggest a fix?
