Well maybe she doesn't speak English so very well and it's difficult for her to write an answer! You never thought about that? I mean it says on her youtube channel that she's from Taiwan. She plays really good! I wish I could play so good!!
I reckon a simple phrase like "Thank you for the comments" can easily be Google Translated, although there are no reasons to think she doesn't know English. Being from Taiwan is a bad one. I certainly do not create accounts on Taiwanese/Chinese forums only to google translate their responses and give no replies. If I did, wouldn't you find that peculiar?
Your playing level is very high, but I think that this piece is still out of your reach. The interpretation is painfully slow.
