What happened to Yahoo Mail lately?

1) a)When I am replying to an email who is replying my email where with I CC’d people, I have to save draft, go to my sent file to copy the CC (I need to continue CCing them, but it doesn’t give the option of continuing the CCing maybe it was always like that) If I just scroll down, to copy it from my email to them, there is only their names and titles where it says who I CC’d.
b)I can’t copy and paste all CC’d people in one shot. It has to be copy and paste one, save draft, go back to sent file and do it one by one like that.

2)If I scroll down to copy something in my part or the recepient’s email, the curser goes to some random place in the email exchange including the time stamp.

3) The formatting that I used, larger font, text color, italics, etc, not there when I get their reply. At least it does remain in the “sent” folder
