You are not submitting a Pokestop/gym, but rather a Wayspot, and each Niantic game chooses which Wayspots are in their games. If there are any other Wayspots nearby already, it’s likely that the S2 cell may be full, and the Wayspot will not be added to PoGo. It’s possible that it may be added to other Niantic games, as they had different rules, such as Ingress having a 20 meter rule.
