Good day and welcome to the forum!
A bug has been impeding sync to Pokémon GO as of late:
Hello Wayfinders,
Please be aware that the sync between the Wayfarer Map and Pokémon GO has been down for a few days. The team is aware and investigating the issue. This issue is not impacting any Wayspot creation, updates, or removals on the Wayfarer side but please know that the changes will not be reflected until the sync starts back up again. I will keep you posted as updates become available.
Thanks for your patience while we work on fixing this issue.
Also as mentioned in the acceptance email, not all accepted wayspots get into the game of choice
While some nominations may be deemed eligible by the community of reviewers on Niantic Wayfarer for inclusion into Niantic’s location database, they may not necessarily be added into every Niantic game. After a nomination is approved by reviewers, there is an additional automated review that determines whether the nomination is an appropriate fit for each particular Niantic game. Each game has their own set of criteria for this step, so some nominations may be accepted into one game but not another.
The most common reason that an eligible nomination is not added to Pokémon GO is because the nomination is too close to existing PokéStops or Gyms. If an existing game location is removed or the criteria changes, the nomination may appear within Pokémon GO at a later time.
Please keep in mind that while this is a common reason, it is not the only one.
For rejected nominations, you can screenshot the full details here so the community can give their thoughts about its eligibility or how to better attempt the nomination.
Hope this helps,
