Prior to microsoft issueing Cumulative Update KB4284848 Windows 10 v1803 Build 17134.137 on Tuesday June 26 Now TV worked for me using the NowTV player app (not the one from the windows store).
After installing that update, I can log into my account in IE11 ( latest version) but when I go to MyTV I am greeted by a blank page even if I refresh it. The same happens if I try to view any content (movies and entertainment) from the menu on the top left of the page.
This is occuring on two Win 10 Pro pcs running Windows 10 v1803 Build 17134.137 and both fully patched that worked before this update.
My question is, is this issue known to NowTV as it's highly unlikely that two pcs that ran NowTV without issue before this update now seem crippled by it.
