Inappropriate pop up ads

My kids love this app and so did I, until an ad for the app Episodes came up, featuring two girls scantily clad asking "what should we do next?" As a mother of an 8 year old boy, and two daughters, I am very disappointed ads like this are allowed to come through an app rated for kids 4+. Its been deleted. Id give it zero stars if I could.
