Attempting to generate any image at all with Firefly while working with a sample image results in a permanent pulsing row of empty buttons waiting to be populated by the AI. I've waited over 5 minutes with no result from a simple prompt 'an eagle soaring in a blue sky behind the man' with a starting image of a man and an empty background. This is my third attempt to do so. I am using no plugins which would preclude scripts from functioning and the rest of the editing interface works well enough.
