I am learning Japanese for a few years, and last week I have started with Skritter on my iPad. I began with kanji and the writing exercises were no problem. Today I wanted to repeat some hiragana. I have a hard time writing ぬ and の so that the app approves it. The app gives me no clue what I am doing wrong. Like I said I practiced some kanji and other hiragana writing without any problem so I don’t know why writing ぬ and の gives me a hard time. Am I overlooking something? Is the app more strict when I try to write these characters?
I am using version 3.3.5 of the app on iOS.
