I’ve started using Playfab again (we were using it a little last year, then dropped it) and am trying out the Entity file system for cloud saves.

I noticed that if the upload exceeds 16K, it fails like this:

`NotImplemented`  
Value provided for Transfer-Encoding is not implemented.  
status = 501

My best guess is that this relates to how chunked encoding is used for payloads over 16k [since 1.2.166](https://forum.defold.com/t/defold-1-2-166-has-been-released/64558), and maybe Playfab requires gzip or something else. I’m not enough of an expert in HTTP to know where the fault lies here - if servers are required to support chunked encoding. Does anyone know?
