Last week Google moved the MCC link and drop-down box up to the top of the screen and now I’m seeing these cute little icons in their own column of the MCC dashboard.
The red one is for critical alerts in your individual client accounts. In this case, a failed payment method.
The yellow guy is for the
annoying less important alerts, such as a campaign that has ended (even though it was set to end and ended right on time).
Looks like the all-seeing eye of Google has decided to focus its gaze on the MCC interface yet again.
