Warzone 2 free week

Hey guys, so warzone 2 has a free week of multiplayer for everybody and that i want to play it, however it doesnt let me. It says i have to have xbox reside gold, however prior to now i had no hassle enjoying with it with out it and that i don’t wish to pay for it. Anytime i attempt to launch it, it redirects me to this web page, any thought how one can repair this? I already tried to reinstall, arduous reset, however it simply wont work..
