Spell checking doesn't change if I change the language

[robertsawko]

My problem is identical to #116. I am on iodéOS 6.0, Android 15 and I am using their version of HeliBoard, 2.3-iode.15. I use Polish and English keyboards, just as in the other issue after changing to a different language, removing all text, new words are all underlined despite correct suggestions.

My phone is Fairphone 5, but I have a friend who uses FP3 and same system and also sees the same issue with Spanish/English keyboard.

Please advise.
