I am currently facing an issue with sign in / sign up for my app. When trying to login or create a new account, I get the error ‘Your API key is invalid, please check you have copied it correctly.’ However, I have made 100% sure that I copied the API key correctly from Firebase.
I have searched this forum and have seen that people have run into similar issues but I have not seen a clear reason as to why this is occurring and how I can fix it. Below is a link to the project. Any help would be much appreciated.
