Dynamics Portals update has affected my JavaScript on Bing Maps functionality

Hi there,

Due to the recent portal update being deployed, we have noticed a few problems with the update that have broken our JavaScript 

Currently having an issue where my bing maps is now defaulting to the "road" view rather than "aerial", despite our code specifying " mapTypeId: Microsoft.Maps.MapTypeId.aerial,"  which was working before the update.

Also we had an orange "pin" before, however now this is a purple dot? Is there any way to get the orange pin back rather than having the purple dot, as we preferred the look and feel of the pin.

As an additional question, is there any way to stop a user from dragging the map to move without the pin?

Kind Regards
Josh
