How can I sign in to my microsoft account on the Xbox Cloud gaming app on the Meta Quest 2?

I just installed the new Xbox cloud gaming app on the Meta Quest 2, but after i’ve connected my controller and i try to sign in to my microsoft account it just loads for a few seconds and boots me back to the previous screen. Either that or it will let me try to sign in but just have no effect at the end. Any help please?
