Hi,
My code has been working fine until recently (about 2 weeks ago), I have experienced a very strange error.
I have always got a fresh AccessToken before calling the API. However, I always get "<totalNumEntries>0</totalNumEntries>" for every service I called. There is not error message, but simply "<totalNumEntries>0</totalNumEntries>".
Here is a sample of the response for "AdGroupCriterionService":
After many hours testing, by accident, I changed the AccessToken to a fake AccessToken such as "ddddddddddddddddddddddddddddddddddddd" to try, then I can get the correct response data from the server.
I just cannot believe this, it completely does not make any sense. I am not sure if this is my problem, or an error from Google.
However, by using a fake AccessToken only works for some accounts, but some accounts still did not work no matter what I do.
I really need your help on this.
Many thanks.
David
