This!.....but especially this:I think there is something to be said for keeping good maintenance on your phones in the beta cycles. Takes a little extra time but the rewards are worth it.
Like, when you get to the end of a cycle, do a clean restore on the official build, ready for the next beta increment.
If an app is playing up, delete it, and reinstall. Don’t wait for an update.
Hard restarts and network resets after new beta installs.
For me, doing the above and using IPSW installs has been great on iOS15. I’m honestly not seeing 75% of bugs that get posted. If you have a phone you just keep chucking beta after beta on, it’s gonna be F’d without any care.
