SharePoint online workbench not working using Edge

Question

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!

Any ideas?

Answer 1

It's a known bug that already reported at Testing SPFx on SharePoint Tenant (From Tutorials) does not work in Edge Browser

The workaround,

• Continue to use IE 11 or Google Chrome!.
• Add the localhost URLs as exceptions as suggested in the above official link
