Is there a quick tour for the OpenWeb application
Yes. Located here.
Can I use OpenWeb on my smartphone

Yes.  The new version of OpenWeb is useable on any device, including desktop, tablet, or smartphone capable of running current internet browsers.   

What is going on with the Silverlight Version of OpenWeb

The old OpenWeb application uses Silverlight, a technology that was retired by Microsoft.  Because of this, modern web browsers are not capable of displaying the old OpenWeb.  This resulted in a complete re-write of OpenWeb from the ground up.  The new Javascript OpenWeb is under continuous development and offers compatibility across all modern browsers, including smartphones and tablets. 

Can I still use the old Silverlight Version of OpenWeb

Yes.  The old version of OpenWeb Silverlight is still available for the time being.  We are working on retiring the application.  If you are trying to use the Silverlight Version of OpenWeb you will need to open the URL using Internet Explorer 11 or earlier, with Silverlight add-on installed.
