Public Betas Are Filled with Bugs
Let’s say that you’re happy to wait for the public beta that’s available to everyone. Even here, you’ll run into a lot of risks. That’s because public betas are also notoriously buggy, and may be filled with so many problems that (like the developer betas) they could brick your device or make using it such a pain that you have to revert.
We saw this in clear detail with the iOS 13 beta, which was an incredible mess when first released. Your device is likely to crash frequently, or at least have apps that crash. New modes may not work or may cause problems when they do work. Specific features like audio or syncing may not work at all. And since it’s a beta, there’s no easy fix for any of these bugs other than waiting for Apple to do something about it.
