I’m on family sharing but I couldn’t use Apple Arcade. It says Subscription required.

I’m also having this same problem and I chatted all day with Apple support about it and no fixes were found. They have no clue what I was talking about. My Apple Arcade subscription worked for awhile and then one day it wouldn’t work. The games I have still work and everything else included in the Apple One subscription does as well. This is frustrating…

First: Check your Settings -> AppleID[Name] -> Family Sharing to see if “Arcade” is listed.

If it’s not, have the family organizer or Arcade subscriber include you in Arcade.

Did the organizer get a family subscription? Have you tried logging out, restarting, and then logging back in to see if anything changes?
