Error message when uploading video to collection

[PlayfulPixel]

So I'm in the Collections, managing the collection.
I've clicked on the Add Media and attempted to upload a video, and received this error message.

What is interesting is that I have already uploaded this video to the product page. It's a MP4 video, 2.36 MB in size. Is this a technical error or something else?

@PlayfulPixel I believe adding videos to collections is not something that is available at this time - hence the error.

Sara - you are a total Rockstar! (How do you remember all these things?)
And so perhaps I am in front of the curve for the very first time??  Crikey..

@PlayfulPixel Not sure whether collection videos will ever be a thing - but you never know
