I've been using supermetrics uploader successfully for months. My cost data stopped showing in Google Analytics as of 1/20. I'm seeing the files being posted to Google Analytics, but the cost data is no longer showing up in reports. Any ideas for troubleshooting to resolve?
It says Source authentication error, so there's a problem with your authentication to Bing. This can occur for example if you change your Bing password. To get the uploads running, you will need to reschedule them.
