My now tv app on my iPad will allow me to access programmes but not play them. It comes up with an error message (0xfde0001b) stating I must restart the app (which I’ve done several times) or delete and reinstall (which I’ve also done several times.
There has been a few bugs going round the apps for NOW which has been highlighted by staff and other forum users that a fix is being looked into. Thankfully and touch wood I have escaped it so far!
Not sure if this link will be of use
Best option is to report directly to staff, my suggestion would be via email as you can send videos/pictures. See below picture for address.
Or jump onto live chat, by clicking "chat online" within the green box, not "get help quicker" as this is a bot.
Not sure if you resolved it, but for future searches for this error if helpful - I contacted nowtv online chat support here: https://help.nowtv.com/article/how-to-submit-a-complaint [they make it really difficult to find] and they advised that its something to do with a glitch on the number of devices you have on your account. There is no option to manually remove a device but the online chat person was able to do it for and now it works on all devices.
