Why does the new iOS update hide the equation when using scatchpad?

When you access the scratchpad, the equation disappears.  This is very inconvenient because now you have to remember or write the equation again when you are using the scratch pad.  This is not the case on the web version.  The equation dims but doesn't disappear completely.  It used to do that before on the iOS version but the new update has changed the scratchpad function to hide the equation instead of dimming it.

iOS version

iOS Version  - Scratchpad

This is what happens when you access the scratch pad.  The equation completely disappears.  This is very inconvenient because if you have to memorize the equation you were working on.

Web Version  - Scratchpad

The scratchpad on the web version only dims the equation.  It does not disappear like it does in the iOS version.  This did not happen before on the older iOS versions.  The new iOS update has changed this function while using the scrachpad, it now hides the equation.  Please change it back so that the equation does not disappear.  Thank you
