I don't get how to make this generator work. I guess it might take a long time, but it remains on 'Generating', then at a certain point the whole plot of the scene, developed from the much shorter prompt, appears on screen, but thr 'Generating' stays there forever. A video player appears, but with that 'content not found' icon as the play button. I have disabled every extension and the adblocker for the whole domain, so it shouldn't be that. I also tried Chrome and Safari, same result. Any help? Thanks
