问题 Got problems getting access to radio control. I followed the MSDN and also downloaded their example. MSDN states that when executing Radio.RequestAccessAsync(); it should pop a dialog asking the user to allow or deny.

Created a new UWP project and all I added was Radio

问题 I'm using mathjax in my blogspot blog and it works well when seen in a computer, but formulas don't transform when seen on a cellphone. I found this other blogspot blog where its formulas can be seen on a cellphone. Why?
