Hi there - thanks for your questions to the community. Here is how you can remove the underline and blue color font for hyperlinks. 

In the style section of your template editor you will find the links setting, you can format them any way you like, including removing the underline and changing the color. See the example below under links:

If you have any additional questions please let me know! 

That section doesn’t show up on my end. Please see attached screenshot. 

It is actually nested in a different section. You do not need to select a text block which is the issue. When you go into your template, you will have Content and Styles tabs, selected Styles and scroll down to find the global link settings. Let me know if that works now!

Got it thanks!
