iPhone Camera Colors Reversed

Hello! I"m a 4th grade virtual teacher and I love using ManyCam. I recently added an old iPhone 7 as an extra camera using the mobile version of ManyCam. It’s all setup and works great except the colors coming out of ManyCam are switched. Blue is red and red is blue. I’ll try to add some screenshots that show the i{Phone is displaying correctly, but when viewed through ManyCam they’re inexplicably switched. Thanks for any advice!
