macOS Sequoia: Question mark and Return key issues

Go to:

System Settings → Keyboard → Text Input → Edit → Input Sources

Make sure the only active layout is:

• U.S.
• (or whatever layout you normally use)

If you see:

• ABC – Extended
• British
• Canadian CSA
• Unicode Hex Input
• International – PC

…remove them. These layouts change the Shift+/ mapping.

Remove everything except your expected layout.

After an update with Sequoia my question mark key doesn't work. Also when typing an email if I hit return to change lines it sends the email.

What do you get instead of question mark? Nothing at all?

Regarding return, are you talking about the Mail app? It sounds more like Messages behavior. Does return work properly elsewhere, like here?

I think that is mostly mistaken. All of these except Canadian CSA put ? on Shift / exactly like US does.
