We have identified and resolved a sync delay for Data Sources that have Custom Date Ranges enabled. Both Basic and Custom Metrics were affected. Manually re-syncing data by resaving Custom Metrics or opening Advanced settings was not affected.
We are already working on re-syncing all affected Data Sources and expect them to sync in the next hour or two.
Affected Data Sources: Google Analytics, Google Search Console, Google Ads, Facebook Ads, and Facebook Pages.
