After login to ebay sandbox as testuser_andreas63 "Hello testuser..." appears in the left upper corner, but also showing the link to login. In the "my ebay" dropdown the only click that leads me anywhere else is the click on "all lists". Any button on the "all lists" page brings me back to the sandbox homepage.
Some months ago, the sandbox never worked as expected (i could never see any item specifics that i have uploaded) and I had to login a thousand times. But at least i could see an item that I have uploaded.
Any help very much appreciated!
