Sharing Doesnt Work As Expected

I rate this app at three because the app for just me works great and I love it. However when I want to share the app show multiple people can add items to the list it really doesnt add up. And preparing for Thanksgiving I wanted me and my sister to be able to update the app as we purchased items for Thanksgiving and we cant even see each others list. App needs to enable family sharing on whatever list we want to share. I want my kids to be able to add something is a recognize it needs to be purchased. This app cant do that. At least not from an app. I dont want to log onto my computer to figure this out. Once they figure out how to share each individual list with family members I may change my rating
