Lost several items from my garage

I’ve lost bikes, wheels and progress updates from my garage over the weekend. I understand it can be caused by logging in using a second device (which I did do). But how do I get things restored? I haven’t got very far with Zwift Support and now they aren’t responding at all. Anyone else have this issue?

Sure lots of people have that issue when they log in on a second device. Only support can restore the lost stuff.
