ITMS-90682: can't contain 16-bit or P3 assets if the app supports iOS 8 or earlier

Hi, I just started seeing this error (without change in assets) in a testflight submission (we have iOS10-only code) - this is the full message (from XCode8)


"ERROR ITMS-906832: "Invalid Bundle. The aseet catalog at 'Paylod/XXXX/Assets.car' can't contain 16-but or P3 assets if the app supports iOS 8 or earlier"


I can submit by disabling iOS8 but need to know if this is a temporary error, or something wrong in our assets.


Thank you
