I love this game but where is the updates

I have had this game for almost 2 years and there have been little to no updates that add anything new. The Computer version has so much more stuff and updates that need to come to this edition. Also whenever I open the app it says Build Expired but there is no way to change that or update. I hope you read this but otherwise I love this game!!
