Hello Guys!
I want to add a Google sign-in to the app, so I created a Firebase project and added the package name of my app, and registered the app...
then later I deleted the project and created a new one and added the same package name for the app and this time I tried to add the SHA-1 key and I was not able to register because of some kind of conflict between the package name and the key, I had only used the package name before and not the key then also it was not registering the app.
so I recovered the old project and deleted the android app in it, hoping that it will no longer give me the conflicting error message so I went ahead and deleted the app, and then the project.
Still, I am having the same error.. also I tried to remove the project from
https://console.developers.google.com/ (Resources pending deletion page) but there is no way to remove it but just to wait 30 days for it to be removed completely even I tried deleting the deleted project from cloud shell (hoping it might work).
Can anyone please assist me ASAP because without the SHA-1 key the google sign-in is not working!
