There is a popular banner format 300x50. Google Adwords lets me to load 600x100 for retina in its interface.
When I load a banner 600x100 in my application and set the DIMENSIONS 300x50 API throws an error:
AdwordsApi::V201502::AdGroupAdService::ApiException: [ImageError.UNEXPECTED_SIZE @ operations[0].operand.ad.adAsImage]
In Google Adwords interface the same banner is added successfully and recognized as 300x50.
Can you help me with the problem?
