I understand that the term ”discover” Some POI means just visiting the POI rather than submitting a new one like it does in Ingress. That’s OK, this actually encourages you to explore which is good.
But I read that discoveries reset at each new season. I’m not sure if that’s a very good thing to do. One month is very short time for most players to explore whole their playing area. Then if you just lose all your progress it would be just annoying. Maybe I’m wrong but that’s what I understood from the info.
