It seems that I cannot create more than one blank sandbox on Neo4j. And it seems also that I cannot rename a blank sandbox. Is there anyway to do that?
No. I don't think there is a way to rename the sandbox. Why not download Neo4j desktop instead? It allows you to create many databases and name them as you wish.
Thanks for hint. I have the desktop, but it seems that it cannot deal with two active project at the same time? So I need somewhere that I can process two active projects parallel. That's why I need one cloud platform for that.
