Test ads not showing up anymore! I did try yesterday first time and I did see banner ad on my first test, then I later tried interstitial ad and get NO_FILL error message and after that also banner ads stopped to working, currently I get always error message NO_FILL : Server Message: no results. Try again in 10 seconds. I am using amazon-ads-5.4.46.jar library and enableTesting and enableLogging is set true and I did setup AndroidManifest.xml and required permissions.
First make sure to update to the latest version of the Amazon Mobile Ads API, currently 5.4.235 for Android and 2.1.9 for iOS. A NO_FILL error can occur if the app is trying to load an auto-sized ad in a container whose dimensions are WRAP_CONTENT x WRAP_CONTENT. This will cause an Auto Ad Size failure and result in no ads being returned. Generally, if this is a screen-width ad then our recommendation for this case would be to change the AdLayout's layout params dimensions to be MATCH_PARENT x WRAP_CONTENT. Auto Ad Size should not be used if a specific ad size is required. Instructions and guidelines for ad sizes can be found here:

They are fully functioning demos of all Amazon Mobile Ad types. These samples should help you better understand how Amazon Mobile Ads are implemented. Code can be copied directly from these projects and modified as needed to quickly place ads in your app. More information regarding these sample apps can be found here:
