Another twist in the sad story of Msft's complete failure to get video to work properly in SPO:
In IE11, an mp4 video added in one blog subsite plays fine using html5 video tag.
Another mp4 added exactly the same way to another blog sub site gets the "wrong file type" error.
A different video that DOES play in IE11 (added the same way) does NOT play in the subject sub site.
How could Msft possibly get this so horribly wrong?
And of course, the video plays fine in competent browsers liike Chrome, Firefox in any site (so far) so it's not a problem with the video.
The issue is one sub site doesn't play any mp4's using IE11.
WHY????
It's very frustrating to see Msft wasting their time on assinine updates that no one has asked for when such basic functionality is broken. MAKE THE EXISTING PRODUCT WORK AS PROMISED BEFORE MAKING DUMBAS* CHANGES!!
I realize that's boring compared to tinkering with "new" experiences etc, and very hard because of how badly made the product is, but it's what users want.
