There seem to be some inconsistencies with the documentation at https://dev.twitter.com/ads/reference/post/accounts/%3Aaccount_id/cards/image_app_download:
At the top it says “Both wide_app_image and wide_app_image_data are deprecated - use image_media_id instead.” But in the parameter section only “wide_app_image_media_id” is mentioned. The latter seems to work, but should we be using “image_media_id”?
In the Mobile App Promotion overview section both the image app card and regular app card are described as having custom decriptions. The screenshots make it look like that is the case. But what is the attribute for setting that text? No mention on the doc page.
