training effect not shown for old owrkouts (last week, months) after update from Fenix 3 to Fenix 5 is that normal ?

I bought Fenix 5 loged in the same account of garmin but not showing any data for Training Effect for last week, month etc....

I used before Fenix - for workouts + Vivosmart 3 to track my sleepeing and calories , so lots of data in my Garmin Connect...

Why they are not used, analysed and shown in trainig effect ? after product update ? 

Strava for example showing my all past workouts and analyse they outcome... 

See price we paying for garmin product I believe the App the web and software schould be much better and well organised!
