Hi Syed,

Thank you for raising this to us. It's odd that you were able to load test ads using our demo units on some devices and not on a specific devices. Could you please confirm the following?

• Is the device have VPN connection?
• Could you please try to configure those device in question as enabled test devices?

Hi Teejay,

Thank you for your response I appreciate that,  your questions are answered below:

• Is the device have VPN connection?
  

• ANS: No

• Could you please try to configure those device in question as enabled test devices?
  

• ANS: Yes, I tried doing that but it didn't work. other then the log that shows up that says to "add this devices as test device" didn't show up when i added my devices as test devices.

P.S. i tried 21.0.0 and 21.2.0 version of  `play-services-ads` didn't work for both.

Thanks & Regards,
Ali

Hi Syed,

Thank you for trying this and for providing this information. Could you please replicate this issue in the sample application you showed me and provide a Charles log of the session, along with a full list of devices this occurs on? This will help me determine what may be going wrong.
