I highly recommend creating a hidden page in your project somewhere where you FORCE v0 to record all requests and all of its responses / answers as if you do not, they seem to be lost forever.
I have determined that roughly half of the money and time spent on this application has been due to v0 simple and bad mistakes.
I once tested it and it made the same mistake 25 times and told me the issue was fixed every time when it was not!
This is called "Hallucinating AI".
You can then go through and determine how much wasted time and money has been spent on fixing v0's hallucinating AI coding.
