I think the prompts are incorrectly processed and often are overwritten instead of appending. There are several example in this design where I asked for USBs 3.0 to be backward compatible with 2.0, and the AI added separate USB2,0 receptacles. I had to spend a lot of credits to clear that. Same with organizing components where I asked for the power relays to be on the long egde and USBs on the adjacent edge - the design became very weird. I don't think the AI understood the prompt. Bottomline - I wasted a lot of credits, and it forced me upgrade my plan - which I did. Even then - I am not having to pay more to buy credits. This is just no good.
