Files won't upload to www folder via Configurator add-on

Tags: #<Tag:0x00007f73ae29b2f0>

I am running Hassio on a Pi 3B+ with the Configurator add-on to manage the files (I have been unable to successfully get Samba running for some reason). I was able to create a www folder in the config directory. I’ve restarted Hassio but when I try to upload a file to the www folder, nothing happens.

I’ve checked to log just after an upload attempt, nothing there.
