If you are unable to see contacts in FYI, try the following steps:
• For iOS users, go into your iPhone settings, scroll down to the FYI app, and make sure the contacts permission tab is enabled (ticked green). The FYI app needs access to your phone's contacts in order to display contacts. For Android users, go to Settings > Apps > FYI > Permissions and make sure the contacts permission is in the allowed section.
• Ensure your device is connected to the internet
• If you know your contact has FYI but you still cannot see them: go into your phone contact list and add +1 in front of their phone number if it is a US number. If it is an international number, add + and the country code to it. (Example: For UK phone numbers, add +44 in front of the number.)
• Go into the Contacts app on your phone and make sure your contacts are either locally stored on your device or are syncing with the iCloud server. Some servers are unrecognized by FYI, especially if your device is a work phone that is tied to a company server.
