You can manage users on your Family plan through the mobile app or the website.
To add a new user from the mobile app, go to "your library" and select settings then tap on subscriptions, manage, and then:
1- Tap on add a family member to generate a link
2- Tap on share under the link to send it to the concerned person
If you want to remove a user from your Family account, simply tap on the X next to their name at any time. Also, you can choose to hide explicit songs from any account you invite to the plan.
To manage your subscriptions from the website, log in to www.anghami.com, select Manage Your Subscriptions from the menu, and follow the same steps to generate and share the link with new users.
