I specified Width & Height properties when uploading my video via the bot API, and that made the video load then play with the proper dimensions on iOS!

Without those, the iOS client seems unable to deduct dimensions from the video file itself, and displays it as a square instead.

Or maybe it was setting the Thumbnail property that helped. Or maybe both at this point, considering how strange the bot API can be at times. Not sure and can't be arsed debugging further, but surely the answer to my issue lies there.
