family sharing - no apps are showing on other family member devices
I've had the purchases tab take 30 seconds to 30 minutes to render in the past. The stores are extremely busy and I'm seeing higher error rates than normal for updates, downloads and such.

I would say, give it 24 hours after you set up the family sharing for things to get sorted out before contacting Apple.

You should also get an email notification from Apple when each person you invited accepts the sharing of apps portion of the plan. They have to opt in to share so everyone should get emails when people join and leave the party, so to speak.

If you want to reach out to Apple - use the iTunes Store Support team as they handle accounts, purchases, billing and such.
