That's not true. Here's a video from a few years ago [showing a superconductor flux pinning](https://www.youtube.com/watch?v=OSojjjvRCR0). You can see from the video it's moving around. Also if it didn't move when you applied a force to it that would be quite the immovable object.
The superconductor can move because it's staying at a consistent height.
The video linked is also pretty good at showing similar behaviors to the sample of LK99 we see claimed in the video: the superconductor can wobble, shake and does return to it's original position (or tries to) - but it's got a lot more mass.
Yeah, it's jumping back to a fixed position which isn't how I thought the Meissner effect worked. Since this seems to be posted by someone reputable though it's weird they missed that.
