At least yall are getting cards from friends, i seem to get none, and i know i get visted

If you are getting visited and they are tapping on cards you will get 3 hearts no matter how many they receive. It seems hit or miss when visiting if you will get a heart or not but when you are receiving then you will get 3 no matter. There are some towns that haven't been opened to visitors - me and my kid updated right after it came out and it took until last night for her to be able to get in to mine, I was able to get in to hers a few hours before her. Be patient, it seems like there will be more than enough time to get all heart associated stuff. When you start getting them they will all come at once and you will feel the love :)
