Sign-ins sent with the application’s older
proj_ ID count toward the same application as its app_ ID. A person who signs in to two of your applications counts once in each. Daily charts end at today. Projected OfflineID usage in Billing is the month’s monthly active users so far; it is not extrapolated.
Mesh SDK
Mesh SDK numbers come from the telemetry your app uploads after it callsenableTelemetry. Final daily numbers arrive after the nightly rollup; until then Today is provisional. A day that has not been computed is shown as a gap, not as zero.
