Imagine that after the app was working perfectly and you could generate images using all the models, now you can only generate images with 3 models after logging in via Discord. All the other models don't work, including the video models.
You can only generate images using: Z Image Turbo base model, Anima base model, and SD 1.5.
For your information, SD 1.5 is free in the regular version and doesn't require a subscription. So you only have 2 models out of all the ones available in the app. You can't even create images with all the Z Image models or all the Anima models. There are three models in Z Image but you can only use one, and there are seven in Anima but you can only use one as well.
Therefore, I think the app has become useless now for new users or for those who accidentally logged out of Facebook. I hope Ela fixes this problem if he truly cares about all users.
