I've just started using Express. I've managed to connect to my Instagram and Facebook, plus made a successful post of 5 images. I want to do an Insta Story using a collage of the images. I can preview this but the publish button is greyed out. What am I doing wrong?
Thank you for sharing this. You're following the steps correctly for publishing on Instagram.
The message on the first screenshot informs that the video format needs to be changed. Instagram only accepts videos in MP4 or MOV that are to be published in Stories. You can convert the format of your video here.
Once converted, you can upload it to the scheduler and try again.
