White Board vs Screen Share

Suddenly Zoom forced me to use Whiteboard versus my trusted Screen Share page. 

Whiteboard is clunky. It required me to pre-choose the Font size before I can randomly write my thoughts, thus ruining spontaneity. My students have no interest in adding their changes to the board, either. Also, Whiteboard wraps text, causing the first letter to capitalize whether it's in the middle of a sentence or not.

WHY was Whiteboard added when Screen Share worked perfectly fine? Please, HOW can  I get use of Screen Share again? 

Yet again, Zoom failed to advise subscribers of another forced change. We are required to adapt, like it or not.
