Yes, i know what Family sharing is. Let me try to explain again. Consider family A and B. A is the organiser. When viewed from A (settings, family sharing - lets call this AF) it says you are sharing icloud storage. When viewed from BF it correctly says icloud storage shared by A.
Now, B has a subscription to Apple tv+. BF says Apple tv+ being shared. And in the family member A in BF, it says A has access to apple tv+
However, in AF there is no mention that apple tv+ is shared by B and has no access to it.
A and B reside in different countries and are connected to different app stores, but that should not prevent sharing the subscription. Indeed as mentioned in BF it says A has access to Apple tv+.
so clearly, everyone is on 14.6 and all the logouts, reboots, logging in etc etc have all been tried.
suggestions welcome.
