I put iOS 17 Public Beta on my back up iPhone XR, and was reluctant to put the new firmware on my other devices, however I found it worked so well that I’ve now installed the Public Betas on my iPhone 12 and Watch Ultra.
I really love Watch OS 10. It’s such a vast difference from the previous version and includes a plethora of improvements that make the Watch so much more intuitive to use. If anyone’s contemplating installing the Beta, then I endorse it wholeheartedly.
