I have multiple languages added to my system languages but ever since the update to Android 14 the spell checker only works for the primary language (the one at the top of the list of system languages). For all my other languages I get red wiggles under each word even after switching the keyboard to that language.

I am currently running UP1A.231005.007.2023103100. According to the release notes this function has fixed a similar sounding problem for the keyboard but the problem persists for me. I am using OpenBoard not the default keyboard, not sure if that makes a difference. My spell checker is set to the default system one.

Does anyone know how to fix this? Or is the problem known to the developers and being worked on?

Small update. It doesn't seem to be related to the keyboard because if I switch back to the default system one the problem persists.

    qubit I have the same issue. I use the default GOS keyboard.

    Thanks for the heads up. I solved it by adding the desired languages as secondary system languages in the Language subsection settings. Then, I set the spell checker to use the system languages.
