Update

Microsoft Edge v150 has implemented a blocking policy that prevents all extensions from running on cloud.microsoft domains. This is due to changes Microsoft made to their browser, and it is impacting all extension users including WalkMe. We have escalated to Microsoft and are advocating for a fix as soon as possible.
