samesite=lax is not working with Safari 14.x

My application is hybrid-native. we use native components and some are the webviews embedded in native component. My application's request to get images from the other server with required cookies were working properly till iOS version 13.x. However, as soon as I have updated iOS version 14.X it stops working, the request which is being made instead of iOS application (with the same domain)stops responding with the images.

During investigation I found that if I change the "samesite" attribute from "lax" to "none" it works and images received. I want to know that is this the known issue from safari or this is the new issue which I am facing with iOS 14.x ?

I have found similar kind of issue because of ITP. Attaching link for your reference:
