I think it doesn’t have to do with the update. After updating the game on Wednesday my neighbors were there, on Thursday they were gone. On another device that was still on the Magical Morocco update they were gone on Thursday as well.
There is a solution that may at least bring a few neighbors back. Players need to change privacy settings for the SFP app, but not every player wants to do this, as the SFP app will be shown to all of their friends.
However, even some players who did change the settings, still don‘t show up on their neighbor‘s party boats.
It‘s up to you if you do the change!
- Go to the settings, then tap „Apps and Websites“. Tap on SFP and change the visibility from „Only me to „Friends“. It may work to tap on „Custom“ and choose the names or „See all“ and choose a list, e.g. if you have one for SFP players.
- If the above doesn‘t work you can try to change the visibility to „Public“
You do the steps for your town to show up on your neighbor‘s party boats, your neighbor does the steps to show up on your‘s.
If your neighbor/s have changed the settings, you possibly need to force close the game to see a change on your party boat: >close the game >doubletap the home button >swipe up the app
