We were experimenting whether to do many funnels or one funnel for 180 levels of progression this week. I think at the same time Unity has done some visual upgrades to the analytics page so I’m not sure whether the problem in the screenshot below existed before or not.
As you can see, the drill down part has been mega squished rather than having a minimum width for each column and having a long scroll bar.
Thank you for bringing this to our attention, I have just filed a bug report to address this issue. In the meantime while we are working on this I can suggest creating several smaller funnels instead of one large funnel. You could do something like create a four or five funnels that have thirty or so steps in them or create a new funnel that only fills when players complete every fifth level. I wanted to make sure you could still get useful information from this funnel so I double checked the CSV download and it looks like it contains all of the correct information.
Thirty levels in a funnel sounds like a good compromise. Besides the bug, we realised having teeny graphs was a bit awkward as well to see which excact levels had dropoff
