Allow date formats other than US
At the moment, when you upload a video, the date format is US (i.e. MM/DD/YYYY).
This is an issue for countries that use the DD/MM/YYYY format as when you get to a date like 01/09/2015, users will assume that the video was uploaded in September. This video would then be considered newer than a video with a date of 09/01/2015 which would actually have been uploaded in January.
SharePoint (i.e. the Platform Office365 Video was built on) can handle regional date formats so there no reason the Video Portal cant either. Its such a simple, yet fundamental, setting that it should have been considered from the moment the Video Portal was conceived!
This is the last remaining issue that prevented me from using the Video Portal over using a SharePoint Asset Library.
