Standard Warning: This is not aimed at the OP or anyone in particular…
Do not use the knowledge of cells to mis-place nominations to try and get them in to the game. You are risking Warnings / Suspensions on both Wayfarer and GAME accounts.
Knowledge of cells should only be used so that you are pre-aware whether a nomination is likely to be a stop / gym or a powerspot.
It can also be used where certain points of interest have more than 1 legitimate location. Example: Sports Field. It is recommended to place at the edge but off the field of play. This could give an option of more than 1 cell.
Once a nomination has been accepted and the location is seen as Acceptable you should not attempt to move it for game purposes. This can also risk your accounts. Location edits should only be attempted when the current location is incorrect. Example: From the field of play to the side.
You can see that yours at 49.044397,2.038963 is in the same shaded cell as Panneau d’affichage municipal et associatif des Terrasses at 49.044286,2.039096
On Street View, it looks like this is across the street from where it is pinned, which would put it at the school, and I don’t think it would be eligible there. I will need to leave that part to someone more familar with these things.
Panneau d’affichage municipal et associatif des Terrasses looks like it doesn’t belong there, so if it gets moved to the correct spot, yours will be promoted.
I’ve marked the correct spot with the red pin (not 100% sure, but this looks like the spot)
You need to use the helpchat (the orangle buble, at the bottom right of your wayfarer screen. Now I don’t know the local situation, so please only do it if I made the correct assumption.
I went to take a look and it seems like i made a mistake when i proposed it so yes you are right. You got the good location. I will ask for it to be moved
