Why doesn't family sharing works?
Why can’t I use the family sharing?
Did you meet all the conditions of family sharing and still doesn‘t work?
Maybe it is because you are our new user and still in Rouvy trial period – 14 free days of Rouvy subscription with premium features. Then you don’t need family sharing from your „family master“ – you have your own subscription-trial. But after the expiration of your trial – you could simply use family sharing feature from your „family master“.
How does it look in your app?
