We had to make a few difficult trade-offs to get the visualization framework to a place where it was truly mobile friendly, open for 3rd party custom visualizations and API extensions moving forward. The visualization framework is now completed and should not change again. One of the trade-offs was temporary loss of drill down that you see right now. Our team is working rapidly to get drill down back and implemented in an enhanced manner as soon as possible. In our user studies, we learned few people actually knew that drill down even existed. We want to improve the discoverability, user experience, and capability.
We do have monthly releases. Please make sure that you keep Power BI Desktop updated. There are a lot of fantastic features coming soon.
