From Tech Skipper's "Camera Issues iPhone 14 Pro Max !" posted Friday on YouTube:
So uh, we’re having some issues with the 14 Pro Max camera.
It appears that many popular third-party apps weren’t quite prepared for the iPhone 14 Pro’s new camera technology. A number of iPhone 14 Pro users are unable to take pictures and images using third-party apps like Snapchat, TikTok, and Instagram. These problems include the camera shaking, rattling, and even making physical noises.
My take: This too will pass. FYI, Instagram works fine on my iPhone 14 Pro and there's a workaround for Snapchat posted here.
