@cynthiajoan In my case I try to switch the default firebase app in my app on the fly. I have firebase app for test and for production. And I have a button to switch it. But then the app was not be created for the specified project as intended

This should be consider a bug because when we try to create the app, it should be created with projectID as a unique key, or we might try to specified more data with new AppOptions. And for the current behaviour the name is misleading. It should be GetOrCreate instead of plain Create

Hi @Thaina, I checked the implementation detail, and yes if we see the project name is same with the default name, we will use the default option that set in the json files. I’d like to get more context of the use case that we have the need of creating multiple projects with the same default name but different options, based on that we can discuss if we want to change this behavior.

Thanks!
