I've recently turned 17 and consequently, rated R games have started to appear on the store. I was going to play Nine to Five Early Access, seeing that it was free, but was denied with a pop-up saying "Problem accessing content, You're not old enough to access this content." I tried with HITMAN - Free Starter Pack as well and the same thing happened. According to the age rating system, I should be fine to play these games. I've looked through various settings and Google support pages and found nothing. Any ideas?
Change your age in your google account that you use for stadia.
