I’m trying to follow this tutorial and so far everything has worked until I try to add new item. When I click the add button, nothing happens. My code is exactly what the tutorial tells me to put so I’m not sure what else I need to do. I apoligize for the lack of background. I think the error has something to do with the firebase backend permissions.
