MacBook Pro: message app auto spell and grammar check, auto capitalization, predictive text not working.

I have checked and rechecked that all the auto spell and grammar check, auto capitalization, predictive text, and auto correct features are all turned ON. None of these features have worked or will work after toggling on/off repeatedly.

As well as when I click "enter" on my keyboard, it will not send the message. I have to click into a different conversation and then back into the one I want to send the message in before "enter" will work.

Apple's current advice does not work and I believe it's a bug with the message app that they need to address. Using the MacBook Pro M5 chip, Tahoe 26.7.1

Hi,

You can fix these features by updating your settings in Apple Support under System Settings > Keyboard.

Check System Settings

Open System Settings on your Mac.
Click Keyboard in the sidebar.
Select Text Input, then click Edit next to Input Sources or Text.
Turn on Correct spelling automatically, Capitalize words automatically, and Show inline predictive text.

Check App-Specific Settings

Open the Messages app.
Click Edit in the top menu bar.
Go to Spelling and Grammar and make sure Check Spelling While Typing and Correct Spelling Automatically are enabled.

If these settings are already on and it's still not working, it could be specific system bugs.
