Error notifications are now grouped by importance. The following alerts are distinguished:
Error (important)
Indicates important errors that should be addressed quickly and can usually be resolved by an Ad Manager. This includes, for example, missing content or incomplete campaign creation.
Error (informative)
Indicates errors that are often product-related and usually not easily resolved, such as " not buyable" or "ineligible".
The new notification, "New campaign non-manageable," alerts campaigns that have been created in the Amazon Advertising Console within the past 24 hours that are not manageable by Ad Optimizer. This prevents the setting of TACOS. This occurs, for example, for campaigns of cost type vcpm or campaigns that have theme targets only.
