We've got a lot of questions about the changes on drill down on the service.
Today @GuyInACube published a great article on the Power BI blog about it

How does this change benefit the user in any way? You double the number of clicks for drill up and you have to go through the explore menu instead of having control on the visual for drill down. This makes presenting and analysis so much less seamless. Please bring back the arrows.
Please read the comment I made on the Blog Post. This implementation is a huge step backwards in functionality.
