There is only limited data available now on YouTube Analytics. This situation has been going on for quite sometime now. Reports on this issue also have been sent to YouTube over the past one month.
Data available on analytics is limited to various areas, the locations of likes, dislikes or subscribers is not showing up and also the data regarding how a video is searched is also not showing either.
It is also found that the top geographies are showing up only in United States and not in any other location. This seems to happen across multiple YouTube channels and does not change between laptops or either internet browsers which includes both Safari and FireFox.
