Rotate Ad's not displayed in device

Which Ad SDK did you use (XNA or Silverlight)? What country are you located in? (not all countries are receiving pubCenter ads) Have you checked to see if you are getting any impressions through the pubCenter website? How many ad-units have you set up to run? Some ad-units may have lower inventory than others. Note that it sometimes takes a couple days or so after releasing a new app for pubCenter to consistently send it ads. Are you getting any errors back from pubCenter (under some circumstances, this is normal)? If so, what kind of errors are they (look at the message string inside the error object)?

Hi, I am using Silverlight, country India. Only one Ad-unit is used, it displays well in simulator not in device. I had 2 more Ad units. Both are not displayed in device. I dont know how to check the impressions through the PubCenter. But the same Ad's are displayed in device one month before.

Hi all, I changed region settings on the device as "United States", now it's works well in device also. Thanks!

You should be aware that forcing the CountryOrRegion setting to "United States" is likely a violation of pubCenter rules that could get you banned from using pubCenter. Ad campaigns targeted at U.S. phone users are intentionally not displayed to users in other countries. Likewise, ads targeted at phone users in Germany aren't displayed in the United States.

Microsoft has advised that the only appropriate thing to set the CountryOrRegion field to is RegionInfo.CurrentRegion.TwoLetterISORegionName. Developers should not set it to any specific country name.
