How can I downgrade from iOS 26 to iOS 18 on iPhone 16?

I recently received an update on my iPhone 16 to iOS 26. It’s just great, however, now some things are not functioning for me that did before. For example, when I am on an app I use the screen attachments are not appearing with rewards on it. I would like to go back to the previous iOS 18, and would appreciate some specific steps to do so. Thanks for reading my Apple comment!

Cheers, MJ

I'm not sure what this sentence means.

Downgrading iOS is not supported, but if you can explain more perhaps we can try to resolve the issues. One easy troubleshooting step would be to try force restarting iPhone: Force restart iPhone - Apple Support

Along with the excellent advice from stevejobsfan0123, you might also want to check that the app developer for the app you are referring to and see if their app has been updated to work with iOS 26. If not, that could explain your issue. How to contact an app developer - Apple Support
