It is discouraging that we were not given a lead in period.
This seems to be the move to using Item Specifics which can be read by third party browsers (aka Google).
My method in dealing with this is to go to my Active Selling List each day and see which about to close items have a Note about IS changes REQUIRED.
Then click on the Note which gives me a popup where those changes can be made.
It also allows you to look at the original listing if you need to pull information from there. (I have long descriptions of my books including a resume of the plot and some info not demanded of books, like the name of the cover artist.)
I'm reviewing about 20 a day, of which, in Books, only about eight or nine actually need updates.
It's also allowed me to review pricing and shipping, which has led to a few changes.
