Is there any way we can see what media or pages have been playing?
Yes. Player Reports allows you to query Players on your PLUS! Network account for a list of media and pages that were played between a given time period, and is useful to give to clients.
Furthermore you can schedule to receive periodical reports based on several parameters and this can be emailed to you.
Please note: When you are searching for a specific media playout, you need to enter the name of the media file. Typically you would enter this in the Include or Exclude field so for example you have a piece of media called acquire-player-now.mp4 you would enter acquire to find any media file(s) with that in the media file name.
