"Description" box won't accept formatting.

I used to be able to draft formatted ads in MS Word offline and then paste the formatted text in the "Description" box of a new ad. Now the formatting is stripped out when I paste text, and there are no longer any formatting options at the top of the online "Description" box

 

The problem seems to have occurred since my previous batch of ads in December.

 

Has anyone else encountered this problem?
