Well I know I can use other builds and it will work fine (like build before this one). We had this bug few builds ago ... now its back again (at least for me). Shame! back to Chrome till next build if they fix it. I guess the stupid Icon is more important for them
If your taskbar icon for is not updating to the new logo, just rename or change the picture on your Edge profile and that should sort it out.
well that's confusing, the new logo is on taskbar but when I open it, it opens in a separate task with the old logo
