Possible causes behind no data for Media Time spent, Content time spent metrics could be as mentioned below:
Please check the main and ad server calls are getting fired fine with appropriate gap in timestamps.
-The difference between ts is 10 milliseconds per main and 1 millisecond per ad. The distance between events must be 10 seconds for the main and 1 second for the ad .
-The timestamp values (TS) should be in miliseconds, not seconds
