The expense of using faulty Adobe products

Firefly nust be an incredibly lucrative source of revenue.  Being charged for misunderstood text prompts makes the service unaffordable for students or those of us who are learning Firefly,  I have many times been misunderstood, or through jy fault, have not communicated effectively.  To be charged hundreds of credits each time an edit is made will force me out of the Adobe system when it comes to AI.  I have been using AI products for decades without complaint.  I hope you hear me on this one.
