I would like to be able to have a thumbnail picture (which could be from the video or a specific jpeg or png) so that we don’t get the big pink Microsoft stream. This would be relevant for yammer.
Same thing in Teams channel posts. It's not showing any preview/thumbnail. It would be nice to take advantage of Stream's built in thumbnail to be the "preview" default in any "Share URL to Stream Clips" in any O365 apps. Especially Teams EDU.
