Assets.car can't contain 16-bit or P3 assets if the app supports iOS 8 or earlier?

Question

Has anyone come across this error when uploading to iTunesConnect. Upload precess gets to \"Verifying assets with iTunes store\" the I get the following error:

Answer 1

1. Find in your assets catalog icons with attribute Adobe RGB (1998).
2. Replace it with icon with attribute sRGB IEC61966-2.1

because, it needs to be changed to 8bit sRGB
