I worked in Postman yesterday and when I started it this morning, everything is gone!
Same here. I don’t have any collection and environments any more.
Hey folks,
There is currently an ongoing incident, we’re working on this now and will have things up again as soon as possible.
The updates can be tracked here 
Was this resolved? I’ve logged in to postman today and my collections and environments are gone too.
