Trying to test my app that is now converted from GCM to FCM. If the build variant is release the app runs. But when I changed the varient to debug and ran the app. I got . . .
"No matching client found for package name 'com.deanblakely.myapp.debug'"
After poking around I think it may have something to do with the google-services.json that I got from the Firebase console but I'm not sure. All the posts I found on the subject were like 3 years old.
