Live Photos no longer splitting into .mov files

I have noted that in December the nextcloud team has added support for Live Photos in the IOS app and the server. However, it seems that this has broken the splitting of the live photos into two different files - the image and the .mov file. This has unfortunately completely broken my workflow, as this was the only way that I have found to get live photos split into their component image + movie before importing both into Lightroom.

Has this capability been completely removed or am I missing a setting somewhere? I have tried playing with both the Most Compatible and Live Photos settings, but this just uploads a jpeg file or a file without motion.
