Rclone acd mount - Streaming from split rar on Kodi doesn't work

I’m running Kodi on a raspberry Pi 3 with an amazon crypt mount. I split a 35GB+ movie into multiple 100MB rar files after it failed to upload 3 times (stupid acd :frowning:) but it won’t playback. Is this a known limitation?? It played fine when I tested local LAN playback from my windows 10 machine. Has anyone else had any luck getting this to work?
