I cannot seem to see any information in the "OAuth grant limits" graph I expect to find in the OAuth consent screen settings at https://console.cloud.google.com > (project) > (hamburger menu) > APIs & Services > OAuth consent screen settings panel. This is what I see:
Why is there "No data for this time interval"? This is true both in my dev project and in my prod project, which has tens of thousands of users using OAuth.
Does this graph not show any information for mobile application token grants (Android specifically)?
Can one monitor how close one is to breeching the OAuth grant limit somehow differently? As far as I can tell, this is the only place that Google reports it.
