Once you've connected your YouTube account, the data sync process doesn't typically take a long time. We sync YouTube data every 12 hours (at 12 am and 12 pm UTC). However, there are a few things to keep in mind:
When you first use a new YouTube Metric, up to 36 months of historical data becomes available.
YouTube doesn't return data for reports created within the last 48 hours, so the most recent 2-3 days of data may not be synced yet.
To start syncing data for a specific metric, you need to select it anywhere in Databox. You can add it to your Databoard, Metrics screen, use it in a Scorecard, set a Goal for it, or create an Alert.
