Here is the feedback number FB18122492 . It has sample files and all the info about how I got the final result.

I’ll look through all the samples again but this seems to be an untested case. The Apple 180 samples don’t have lens info and the APMP samples are mono. I need stereo with lens info.

It doesn't work, this is a real pain. it is like there is no rhyme or reason to which window opens first.

I have the same issue only on WatchOS though. Is yours the same?
