After running for 2 years without hitting any quota limits, My app is hitting a daily quota limit on login (firebase phone authentication) which is not allowing any users to use the app and saying "SMS Quota for this project has been exceeded". I checked firebase auth usage and its far way from the free tier limit(10K), and also it's on Blaze pay as you go plan. I also checked Google Cloud Platform quotas page and it shows that all quota are within limit.. GCP support replied the following: "Cloud Functions quotas are all within limits, the quota exceeded messages are coming from another system."
Any idea haw can this be solved?!
