I came across the following sentence

不幸の手紙から、全然進歩しちゃいない

I'm not too sure what the しちゃいない means ( I know what the sentence means).

I know that ちゃ is a contraction of ては but in that grammar I've always seen it
followed by 駄目、いけない or ならない. Is the いない just the negative of いる and can follow
on since we had the て form (as well as は particle) of する？in which case I'm
then not sure of the meaning of just しちゃ...

Thanks.

answer
I searched the expression on Google and felt that it has less to do with
「しては+いけない」。People have been using this expression to describe unexpected
contrasts.

「しちゃいない」＝「してはいない」 means the same thing as 「していない」, and 「は」is inserted to
emphasize the state being described by the phrase 「していない」.

So in this case, the speaker of this sentence really wants to highlight the
fact that there is no progress at all.
