I host the content that some of my users play via the skill. Tracing the audio requests in Wireshark, I can see multiple requests downloading the same content in certain situations.
For example, a resume request will download the entire file, then a subsequent request will download the correct bytes using the range HTTP header. There then appears be another request to download the entire file again!
This is causing high bandwidth costs for me and unessary network traffic for my users. I have a PCAP file if helpful.
