Tango will need to be allowed access to your contacts in the Privacy settings on your Apple device. To allow Tango access:
- Tap on the Settings app
- Tap on Privacy
- Tap on Contacts
- Enable Tango access
If you don't see Tango under 'Contacts' within the Privacy settings, navigate back to the Settings page and tap on General >> Reset >> Reset Location & Privacy. Now launch Tango and a prompt will appear which will allow you to let Tango access your contacts.
If you have contacts that still don't appear in your Tango Friends list, make sure you have their exact Tango registered phone number or email address saved in your device's address book.
