It looks like the Switch version of Among Us had a update called Quick Chat; a mode that lets you select preset phrases to chat. However, I've attached a USB keyboard to my Switch, so I can chat normally fairly quickly. I see an option for "Chat Mode" in the settings, that's set to "Quick Chat", but it's grayed out, and I can't even move the cursor to it. Is there something I need to change in my Switch account to get full chat access?

Best Answer
To "disable" Quick Chat in Among Us on the Nintendo Switch, you must have your age to upper 18.
Changing your age
This is how to change your name according to ESRB Ratings:(Press "Home" on your console before following these steps)
The third step will not work unless you are the admin/caregiver of your own Switch.
Conclusion
Open "Among Us". The age should link to Among Us and change your age/birthdate. Enjoy the disabled Quick Chat.
