"Autocorrect Won't Take No For An Answer" does have a workaround at Settings > General > Keyboard > Text Replacement. If you add the word as both the phrase and shortcut it won't be autocorrected. Apple should still fix the learning behavior of autocorrect, but this workaround can prevent some frustration.
Two other bugs I haven't seen mentioned yet:
- The notes field in the Contacts app on iOS is completely broken. If you start typing a contact note the page jumps around randomly. And if you have a longer note it won't autoscroll to the cursor so you're typing blind. Became even worse in iOS 26...
- Stage Manager on macOS feels very buggy due to inconsistent behavior across apps and windows. Could be great in theory, but in practice frustrating to use.
