Response fields must be included in dimensions
If you use video or player fields (such a video , video_name , player or player_name ) in the fields to return but do not include them in the dimensions, the response items will include irrelevant values for those items and should be ignored. Other values in the items will be valid.
Workaround
Do not include video or player fields in the response fields unless you also include them as dimensions.
"Other" results for device manufacturer
In some cases, you may see a high number of "other" results for the device_manufacturer field. This occurs when the Data Collector does not recognize the user_agent delivered to it with analytics data. The most common cause that we have identified for this is a custom user_agent string created by Instagram, but there are probably others.
