I have been experiencing this problem for a while now. My keyboard is not working properly: usually I have input languages in Korean and Japanese and English, and I can just slide the space bar and the input language changes. Then, after software upgrade, I can't slide the space bar anymore and I can't use the other languages. I have tried checking the input settings and checked and unchecked the input languages but it's still not working. I hope someone can help me. Thank you!
