I've used the slider previously in the Habitat theme, but I recently tried to create a new post and the option is no longer available.
When creating a post, I can click on the Featured Images section --> Insert Image and upload a new image. Previously, once I made my changes and saved them, there was a button to set the image as a featured image. This button is no longer there. If I choose the only button available (Insert into Post) it inserts the image into the post as a normal image. Please advise.
