How to revert iPhone update from iOS 26.1 to a previous version?

I am all fine for change. This is beyond just being less intuitive, more problems and, taking many more steps to do one action. It is also removed many passwords from my keychain and from apps. It is the most absurd yet so , frustrating.

The new version of IOS has completely screwed up my email system and I can also no longer send items to my printer. I need the old IOS before this last update so everything will work again.

do not tell me to accept this nonsense. How dare you.

I get the need to fix bugs and improve security we are all great for that but the new look to apps is awful you keep trying to reinvent a wheel and it’s not welcome
