NEW ZOHO UI BEING FORCED UPON US 5/18/2018

I don't want to use the New!  ZOHO UI.  I like the old one better.

The new one messes up formatting when I forward ORDERS to my supplier.  The new UI is harder to read message lists in my inbox.

Why are we being FORCED to move up to the New! UI???

I WANT TO STAY WITH THE OLD / CLASSIC ZOHO MAIL UI.
