Hello, computers here are set up as Domain computers. Tried to download a theme, pressed Get button and the MS logon screen comes up. If you click the X to get out of the logon screen, it refuses to download (not an issue in 10), and it only accepts a personal MS account, we use O365, it doesn't accept those accounts. I'd rather not use a personal MS account on a work computer just to get themes, nor do I want to create another one just to use for themes.
Either fix to accept the O365 accounts or let the download happen regardless if you choose not to logon.
