Hi Apps Viet,
Thank you for the additional information. We would start by suggesting that you read this
article which talks about new apps that have just been released. The other thing we are suggesting is that if you are seeing this issue on newer android S phones, to add in the <user-permission> for getting the AD_ID if using the current SDK, 20.0.4. After all this if the issue still persist, we suggest then to contact our
Product Support Team , as they have the tools to look into the ad serving side of this.
Regards,
