I cannot share Apple Arcade with my Family.
I have subscribed to Apple Arcade. I am the Family organizer and shared Apple Arcade with the other three members of my family. I verify sharing under Settings > Apple ID on the top > Family Sharing > The Apple Arcade is listed under "Shared with your family" heading > after clicking on "Apple Arcade" > It said Subscriber: Me + Share with [family member 1] [...2] [...3] (everyone)
However, it only works fine on one account but not on others. For example, on another account: when going to App Store > Arcade > There is still a blue button that says "Try it free" (1 month free, then xxx/month)
I attach a screenshot of my account/ member account.
What shall I do to resolve this issue?
