Tacx Activity saved but nowhere to be found !

Hi.

Yesterday and today I have oat two hours rides. As usual when it came to the end I chose button Save and the whole page went to main scree. When I took a look at the dashboard the activities from yesterday or today wasn't nowhere to be found!

I am using a Google Chromebook. When I did test ride twice the ride was saved and uploaded straight away. It seems like long rides are gone. Is there any chance I can restore them! It's so frustrating I have no stats at all. 

I have contacted Garmin yesterday and today but of course no answer ! 

Thank you
