AdSense's defined ad units do not display properly in mainland China, but display properly in other countries.

ton about the customized ad unit can't be displayed in China, other countries are displayed normally:

After introducing AdSense script, " https://www.google.com/recaptcha/api2/aframe "will be loaded automatically , but the script is not accessible in China.

We have created the following ad unit in Google AdSense

Inserted in the following locations respectively:

1.Below the tool upload button

https://www.zhihuilib.com/general/imagecompress

https://www.zhihuilib.com/general/gifcompress

https://www.zhihuilib.com/general/pdfconvertimage

As the above link similar to the following position has been added to the ad unit, before August 2023 can be displayed normally, and after that has not been able to display, according to the official access document to modify a few times the access method, still can not be displayed.

2.News listings, infomercials can't be displayed

The positions shown below are added with ad unit code, and can be displayed normally until August 2023, and have been unable to be displayed since then

Through the developer tool, I found that "https://www.google.com/recaptcha/api2/aframe" will be loaded automatically after referencing AdSense , but this link is not accessible in China, I don't know if it has anything to do with this.

3.The news detail also adds the ad unit, but it can't be displayed in China either.
