I made a post on this a while back.
https://eu.community.samsung.com/t5/samsung-lounge/samsung-keyboard-spelling-and-grammar/td-p/119245...They are so cautious. AI is in a weird spot right now, trying not to get into trouble.
It seems as if the word "inept" is being blocked. AI will block any words that can be seen as insults. Removing that word allows it to be corrected—ironically, it let me use AI for this message even though I included the word again.
I submitted feedback via Samsung Members and was told it has been passed on to experts, but I suppose it's a work in progress for their own safety—AI being a gray area.
I would also suggest submitting feedback via Samsung Members—support—feedback. As Samsung doesn't monitor these forums—being a forum for customers—customer support.
