The popularity of Android Pie did not meet the expectations of Google

The ninth version of the "Green Robot", apparently, does not please developers with its popularity. At least, such a conclusion can be drawn from the fact that after its release, Google stopped publishing monthly popularity ratings of its operating systems. Actually, the leadership of Apple recently followed the same road, in the light of falling demand for new iPhone models, having ceased to publish sales data.
By the way, the latest popularity rating of mobile operating systems is dated October and at that time the “nine” was absent in it, having failed to gain even 0.2 percent of popularity. Now, of course, the spread of Android Pie has increased significantly, but not to the extent that you can safely demonstrate the rating.
