Poor notifications

Why on earth did this app turn off notifications when people need it to add old friends they have removed by accident or not. I hide and Remove people but I am getting hearts via Tsum Tsum game but I cannot tell which one its from. Please fix this notification issue. For some reason, Japans Tsum Tsum version has notifications working just fine. Please turn on. Thanks. Hope anyone will read and help all out.
