A guide and tutorials on how to produce AI images that will be accepted by Adobe Stock. I have used Firefly and Lightroom and photoshop tools to produce images and I keep getting Quality Issues

Please explain why I keep getting “Quality Issues” if I’m using your tools,  Firefly, Photoshop and Lightroom. It’s no fun if your programs don’t produce the QUALITY necessary  for Stock and commercial use. You need to EXPLAIN what and why my image is not accepted so in the future I can produce acceptable submissions. Otherwise what am I paying for? And going to the community for explanations is not really helpful. As they don’t have a clear answer. and you can’t upload the full sized file. You need much better feedback than just saying Quality Issues etc.
