I have some Wayspots that were recently approved but did not appear in Pokémon GO, even after the normal synchronization period.
I checked the locations directly in the Pokémon GO map and there is no conflict with an occupied S2 level 20 cell. Other Wayspots approved during the same period appeared normally in the game.
Could you please check if there is any delay or technical issue preventing these Wayspots from being synchronized with Pokémon GO?
