Google has had automated reviews for a decade now, I think there's just so much volume (I read somewhere in linkedin there's 1000 apps per hour submitted in playstore alone) that is choking the system.

That's an average of 24,000 apps per day.

With that amount of volume, it would be safe to assume that there's more reasons why google just won't accept an app even if it works fine or fits all the public guidelines.
