Cannot get Background Task to Start

Thank you for your response. I have called the uplink function directly and it works – but I thought it would time out when having to wait for 5+ minutes. But I do not understand your instruction to call the background task when the long uplink function is finished. I may be misunderstanding but if call the function downloadMediaFile(file) – on the remote uplink server – and the web side will wait and spin for 5+ minutes then why do I need the background call – I think I just do not follow your instructions.

Thank you,

Jack
