New Pokestop not showing up

Welcome to the forum @Jock93

If reviewers thought you pinned this away from the actual object, they can correct the pin in review. I can’t see it as a portal either to show you where it currently is. You can use the toggle in the Pokemon Go nomination map screen to see where it actually ended up. You have to be right at the place for it to work. It will show as a red exclamation point, like this:

I try to be clear when I share the S2 cell information that the thing you are submitting has to actually be there. Do not just pin it in a cell that is empty. Most of the time reviewers will correct the pin, and pinning away from the actual object can get you in trouble with Niantic.
