As explained in what you read, the problem isn't following the guidelines, and there's not much you can do on your end. You haven't done anything wrong.
The problem is that your game needs to be reviewed by a human before being indexed. This human review can take several days, simply because there aren't enough staff members available to do it sooner, and that's something you can't fix on your end, period.
What can you do?
What you're already doing: not relying on being indexed and promoting your game.
Will asking for help here help?
It depends. I've seen two situations. Sometimes a game gets stuck in limbo for some reason, and getting the staff's attention allows those games to be reviewed again.
But if the game is in the normal process, meaning it's waiting its turn to be reviewed, then writing here doesn't seem to have any effect.
