I have a website that was approved since the first request, I also just delivered another project in which they had the same problem.
This: https://www.freelancer.com/projects/wordpress/Identify-Google-Adsense-Violation.html
Adsense's rejection may be due to different errors such as content, security or others. It would take me 3 or 4 hours to review it, but it all depends on what you find and how big your website is.
Let me know if I could help you.
