As of version 7.8, Contacts Sync requires new users to purchase a subscription to unlock premium features.
IMPORTANT: If you previously upgraded the app, and the app isn't granting you permission to the premium features, that will be fixed with version 7.8.3 that is pending approval from Apple. Thank you for your patience.
Transitioning to subscriptions will allow Contacts Sync to improve more rapidly over time, and to more effectively maintain the app so it continues to work well.
