Got approved 1st attempt on an almost empty site years ago and just got my 2nd "low value content" rejection on a new "better" site

Hi everyone,

I recently launched a new website and applied for AdSense and just got my second rejection with the famous "low value content" message (no specific details). The site has been live for about 3 months, I've added blog content and is starting to get some decent traffic.

About 6 years ago I had a completely different site (now discontinued), it was basically a simple web music player that played files from your phone, and it got approved on the first attempt. That site had way less traffic, almost no content and no blog articles at all.

I've seen other posts here saying that you can keep applying and sometimes they approve it after a few attempts, can anyone confirm this? Or is there any specific update recommended to get approved? Would really appreciate any insights. Thank you!
