I ran a quick test, since I was curious as to what was happening. ProRes Proxy file copied from an Alexa clip with lav + boom on separate tracks, left + right. I brought the clip into FCPX and then uploaded it to Frame directly from the FCPX browser using the extension.
I did two uploads – one with the clip set to stereo and the other set to dual mono. When I played back both files, using the extension panel, as well as the web portal, I still heard the channels separated on my speakers. I downloaded both files and they were the same as uploaded – ProRes Proxy with audio on 2 different channels.
So my question is, are you going through a project timeline first? Could it be that your camera clips are ID’ed as dual mono? This would sum them to mono on a stereo timeline. If so, that’s completely normal and the extension is doing everything correctly.
When I uploaded a clip using the Frame H264 share setting, dual mono audio was summed. IOW it reacted as if it had been placed on a timeline and shared. When I set the clip to stereo, the separate left+right configuration came through correctly.
From what I can tell, the extension seems to be performing as one would expect.
