Fiona's official YouTube channel can be found here:
youtube.com/user/fionaappleVEVO/videos
n.b. This doesn't seem to be linked to any of the individual videos and (at least in Europe) you can't subscribe to it.
There is also
youtube.com/@fionaapple
but that also seems to be broken/empty, YouTube seem to have no interest in fixing issues with the official channels.
