Known issues for PC
Extensions in Microsoft Edge do not work in this build. Extensions may appear to load but will not function as expected. This issue should be fixed in the next Insider release build we release. If you depend on extensions in Microsoft Edge, we recommend skipping this build. You can pause Insider Preview builds by going to Settings > Updates & security > Windows Insider Program, clicking on “Stop Insider Preview builds”, and choosing “Pause updates for a bit”.
