Problem with Microsoft Windows 10 Mobile app

You seem to want to argue over a near seven month old post for some reason. Again do an internet search using your favorite search engine and you should find numerous discussions on people having trouble with Microsoft Edge. Including problems loading some websites. Do I have a specific list of websites? No. Like I said in the other thread where you are arguing over this for some reason. Things have gotten better for Edge. But if you insist on continuing to argue then you can see some of the following links, both older and more recent, that detail some others having trouble with Edge.

Bottom line is that Windows Phone is no longer supported by WD, and hasn’t been for well over a year. Don’t like it? Contact WD directly (https://support.wdc.com/contact_phone.aspx?h=4) and complain to them about their lack of support for a currently dying platform. Windows Phone has dropped from 2.30% in August of 2016 to under 1% (0.99%) in June 2017.

You can continue to argue over this, or you can choose to move on, if you haven’t already, and use a mobile platform that has (for better or worse) more broad support. Including support by WD.
