I was having the same problem and found a solution.
Once you click "Grab your offer now!" it opens the web page. In the web address box the NOW TV pass code is at the end of the address, copy it and go back to manage your passes and paste it there. It worked for me.
I had the same problem and I’ve seen the solution to this that the pass code is at the end of the web address but the web address is so long - what am I looking for when looking for the voucher pass eg how many letters is it. Just to give me a clue. Thank you. 3dNvpILZgIksst4sUht5mSZFEqNR7Xs99rZUOQd2qyIic%3d
Hi @Anonymous User
There is no NowTV voucher code embedded in that URL address that you posted.
Was this the URL address when you followed the NowTV email link offer when it directed you to your account ?
