You're not alone. I have 2 websites with the same problem. Rejected after just 1 night.
However my problem seems to lie with the domain name containing Google's "brand name". I still keep the domain name, but change the Website Title. After resubmitting the request for approval. I had to wait up to 3 weeks to receive an answer.
And damn it. Currently, I have 3 websites that were denied approval for the reason: Low Value Content. Although the article was compiled and rewritten by me manually, it is of very high quality. I have never encountered a similar situation before. I have had 50 websites approved for Adsense in the past. Currently, new websites are being rejected and have to wait 2-3 weeks to receive a response from Adsense. Damned
