We are seeing slowness and failed queries for Google Ad Manager at the moment.
This appears to be a problem on Google’s side, with their report service and APIs, and there's nothing we can do to fix that. We are waiting for them to address all the issues with their service.For full details of the issue and the current status, please see the Google Status report:
Also, some users have been getting warnings that Supermetrics is using a deprecated version of the Google Ad Manager API (specifically v201805). This is nothing to worry about. We are aware we are using the older API version and are working to update the connector to a newer API version before the official sunset at 31st of May 2019.
