If we had the luxury of punctuation this would be: The answer - fortunately - is yes.
As we haven't, I think the preferred order should be: Fortunately the answer is yes.
This obviously isn't a big issue - just thought I would share it as word order is quite a subtle thing, and is clearly treated very different in English and Italian. Is their agreement on this?
It's of importance mainly because, in English, "fortunately" is (usually) a sentence adverb. The added punctuation is needed because it's not in its natural place. Note, however, that a comma is often used even when it's at the beginning of the sentence: "Fortunately, the answer is yes."
Of course, it's mostly moot because DL's parser ignores punctuation.
Duo is supposed to be a free language platform. What do you mean by "charging"? Hope that you are not being charged. However, I have noticed that I have recently started getting annoying ads popping up when I am on Duo, both when using my lap top or using the Duo App on my phone. The justification is that it helps keep the learning free. This is very annoying, Duo!
Germanlehrerlsu - Ads started popping up on my laptop in last month or so, though I have been using it for a year and never encountered ads previously. I had been singing the praises of Duo to family and friends, adding that it was an enjoyable and useful free service. I was wondering whether Duo was aware of those ads at all and whether they originated from Google or the Duo App trying to jump on the bandwagon and make money. I wonder how I can get rid of them. ocf781 - Yes I also encountered that recently when practising Duo on my phone using the Duo App. I simply closed the App and continued my lesson on my laptop. Not sure why it thought I had run out of health when I had over 2000 Lingots at the time.
