There is a problem since 16.01.2018 with data synchronization between index scale and connect mobile app. From 16-th of January it collects (displays) just weight, bmi and loss /gain. In weight card it display also body fat and water.
Weekly /yearly graph are without data if you select anything beside weight! ciq.forums.garmin.com/.../1311561.jpg ciq.forums.garmin.com/.../1311562.jpg
