magic keyboard is not allowing me to type in Korean

I am using the magic keyboard with iPad Pro. It works fine with all other language keyboards (Japanese, German, French, Russian) BUT Korean, since the last Monday. It was working fine until then. For some reason, if I try typing in Korean, Magic Keyboard would only allow me to type in English mode.

I don't think it's the iPad, because if you just use the keyboard on the iPad itself, I can type it in Korean.

Does anyone know why this happens and how to solve this?

I don't even see the category "magic keyboard" so I am putting it here.

Please help!
