Cannot change language on iPad Pro using Universal control via Mac

Thanks for your kind reply. My Mac actually have Caps Lock to change language between Thai and Eng and the same setting for iPad. However, with the setting that use Caps Lock to switch language, it doesn't work on iPad when using Universal Control. The issue found was that the language keep changing from Thai / Eng.

So, I have to disable using Caps Lock for language switching and use the Globe key instead. Nevertheless, it's not work well on Mac. So, the the most convenient set up should be Caps Lock. But I faced issue with auto language switching.

Any advice on fixing or this is a bug of Monterey? Thanks.

Dear Tom,

Thank you for your kind replay and advice.
