in settings there is a button to slide if you want quick-add for new neighbors on or off. Mine is switched off by default and there is now way I can switch it to 'on'. I can switch, but it immediately switches back to off. I tried this for several weeks now and yesterday I was discussing it with some neighbors. It appears that some can switch quick-add on/off and some others (including me) can't. Is there some other setting(s) that might cause this? Or is it a bug? I play on IOS.
