Lacerte does not default to any one browser; the browser it uses to open the hyperlink is driven by your default apps setting for web browser.  Having said that, Edge is not among the browsers Link supports, as outlined in the article appended.  This means Link may not render or function correctly if Edge is used.  If you haven't already, you may like to check your Default apps setting for Web browser just to be sure.

Thank you for this clarity. Then it makes sense for me to use Chrome as my default browser.

NP.  Glad you find it helpful.
