CNAME not working for Transformation image

Hi Team,

CNAME is working fine for original assets location and it is not working for transformation/optimization image paths.

I will explain with examples:

Original/Actual assets path:

https://res.cloudinary.com/SAMPLE/image/upload/sample.jpg

After configuring CNAME:

https://assets.SAMPLE.com/image/upload/sample.jpg

But for Optimized/Transformed assets path the CNAME is not reflecting.

Optimized/Transformed assets path:

https://res.cloudinary.com/SAMPLE/image/upload/c_fit%2Ch_430%2Cw_480/100...

After configuring CNAME(It is still the same, CNAME is not reflecting):

https://res.cloudinary.com/SAMPLE/image/upload/c_fit%2Ch_430%2Cw_480/100...

After configuring CNAME, expected URL is below,

https://assets.SAMPLE.com/image/upload/c_fit%2Ch_430%2Cw_480/10045386-h_...

Kindly let us know when this issue will be fixed and new release rollout.

Thanks
Palani M
