I'm about to develop a SharePoint modern web part but I cannot test my web part online using Edge (IE 11 works fine). I have deleted the gcb-serve-data folder and reinstalled the cert, still I get this message "Your web part will not appear in the toolbox. Please make sure "gulp serve" is running in a web part project."
No build error. Working just fine using Edge locally, and IE11 works online but I don't want to use IE11!
