Curious question, if two way stops are in the same s17 cell, only 1 will show up, correct? If i move one into a new s17 cell, are the moved is accepted, would both stops be in game? Since they not in the same cell?
Yes, only 1 Wayspot per L17 S2 cell in PoGo.
Please note that all locations must be accurate, and moving a Wayspot to an inaccurate location just so that it may show up in a game could be seen as abuse, as it could manipulate gameplay unfairly.
