My application is on dev-server. It is working in all platforms except Facebook app browser in mobile, although its working on chrome mobile browser.
I wasted so many hours and after that I discovered this warning regarding SameSite Cookie:

I've read instructions from https://web.dev/samesite-cookies-explained/
My project is running by Angular. I don't know whether I have to set the set-cookie as ideal Cookie or in Request/Response header.
I've already tried as Request Header like https://angular.io/guide/http#adding-headers. And I don't have idea how to set-cookie in Response Header.
I also don't know any other alternatives.
