Same thing happened to me, try recompiling the SASS or if your using the .css out of the box, update your reference in your .html file. Solved the issue for me.

I had observed a similar behavior while trying to upgrade to 2.1.0 RC1.
In my case, the app.html page had references to the css file of 2.0.1 version. Modifying the css reference to point to the 2.1.0 RC1 version solved this issue for me.
