My Contacts are not showing up when I'm preparing an email.
Apple requires an approval from the user for any App to access your Contacts on the iPad or iPhone. You need to explicitly give approval for FatStax to access your contacts by tapping "Ok" when asked in FatStax. This happens the first time you try to add a contact to an email.
You can also set that approval through the Settings on the iPad or iPhone. You may need to do this if you skipped or did not tap OK when the app asked to access your contacts.
3. If the switch isn't green, that means the App doesn't have access to your contacts
4. Return to FatStax and test by adding a name to the Contact page when addressing an email
Contact firstname.lastname@example.org if you are still having trouble.
