Japanese Kana input on iPad
I am using an iPad pro with a Logitech Create keyboard.
I set up both a US English and Japanese Kana - (with Kana keyboard) languages. In Japanese, the US keyboard setting is using Romaji input, not a direct kana input. I would expect this under the Japanese - Romaji setting. The kana keyboard is mapped slightly different from my US keyboard stickers, namely the ろ へ む ゜keys. I use these same labels on my Windows based laptop with no issues.
Can anybody advise me as to why Japanese - Kana (US keyboard) is using Romaji input? If I want Romaji, shouldn't I select Japanese - Romaji? Is there some sort of issue with iOS? How can I get a direct Kana input with a US layout keyboard?
I realize that Romaji is the preferred method, but I plain and simple personally prefer to use kana directly.
Thank you for any advice.
