We're using the youtube data api v3 and have been for quite some time without any problems. Recently, we've been getting this 403 exception:
The request cannot be completed because you have exceeded your <a href="/youtube/v3/getting-started#quota">quota</a>.
In the google developer's console, it says that we are still under the quota (currently it states "units/day 163,817 of 50,000,000").
Am I missing something about how quotas work?
