I guess your problem is that you have to add 3 sha1 keys in order to work. I had a similar problem, checkout me post stackoverflow.com/questions/51360250/… - Kwnstantinos Nikoloutsos

After releasing the app, the play console generate new certificate which is called "App signing certificate". It contains the SHA1 certificate that you require. It can be found at:

Released Management->App Sigining on your play console. Copy it and paste it in your firebase app -> project settings -> add sha1 fingerprint.
