I found "MacOS 10.1" visitors increasing unnaturally, and its "User Agent" values, cross-tabed prop, includes "Mac OS X 10_15".
Are there any kind of misdetection?
I contacted customer care about this issue.
They told me that it was a bug. A few days later, it seems to be fixed.
@_kunihiro, could you share how you came to that conclusion, what dimensions you analysed?
