When a Microapp is displaying posts that include a multi-image post, only the first image of the multi-image post is displayed.
- Member Experience | Microapps
It is expected that when a Microapp is displaying a multi image post, all the images are accessible by clicking the "pips" at the bottom of the displayed image.
Currently the best-known workaround or resolution to this issue is to upload images into individual image posts.
