There are a couple helpful youtube videos of crossers that have great tips. A few that I've seen have taught me:
- villagers can ping you to give you something, or to buy something from you. SO, fill up your inventory with things villagers won't buy, like flowers, so you can cut down on those pings.
- related to the tip above; make sure the amount of bells you're carrying is low, so they won't ping you to buy something.
- 10 min wait time I've heard makes them more likely to ping
I hope this is helpful to you. <3
Good luck getting those PWP!
