Q: I was logged in as a guest. When I wanted to add my selected products to the order, I was requested to login. After a successful login, my search results and my defined AOI were gone.

A: Your AOI is still there, even if you see the entire world. Just click "Zoom to Your AOI" and your previously selected AOI will return. The search results are truly gone. Therefore, you have to search for and reselect your products again.
