Does not connect to my Fitbit account. – Sync for FitBit Health Review

When I try to connect to my Fitbit account and reopen FitSync I get and error identifying "Require Health Kit Access", but there is not a way to link within the app. When I go to iOS setting and attempt to allow access to Health Kit the FitSync app doesn't show up in the list. Wasted my money and time trying to get this to work.
