3- Grammarly behaves as if you aren't logged in. If you click on the extension icon, you get a message that says "Grammarly is active, but key features are missing -- Sign up now to unlock the following..." as per attached image
PS. I have checked and double checked, the extension is activated. I have also tried uninstalling and reinstalling the extension. I have also logged out and logged back in, all to no avail.
@Balaje_Krishnan - Just a heads up that my Grammarly started working this morning (04/26) in Edge Dev release. Since Dev did not update today, I would presume that the Grammarly extension was updated in some way. At any rate, some form of spell checking was all I was waiting on to make Edge Dev my primary browser.
