I don’t know why but when I first upload a post the images work perfectly fine. Then randomly they just break. No matter how many time I re-upload the images, just give it time and it will break again. It is getting really tiresome. The whole point of the plugin and paying for pro was to make things easier for myself. However, its created a lot of work. It only happens to images in the section of my post that is marked as patreon only. Also, all posts that are not locked the images show just fine.
Did you ever enable image lock in plugin settings?
