Google Play/Sony Select 4K movie offer

[OnamCh]

Hi all, I purchased a XE93 mid 2017 and when I launch the home screen it suggests I can get two 4k movies for free however when launching Google Play Movies I don't see the option to redeem this offer? If I were to add the movie to basket and attempt to checkout, it suggests it will charge my card. 

I noticed other people have experienced this too but after restarting or an update it suddenly appears.. I have done both to no avail. Is this an offer whereby although it says its going to charge my card but it actually doesn't?

Thanks in advance.

I’ve managed to redeem one of the two offers. But the offer vanished after first purchase so I can’t get the second movie... 😞

Did it ask you to present a debit card or did the value appear as £0 when checking out?

If you want to redeem this second offer, you need to delete your google account from the TV and use another account, as your first account will be linked with the previous offer.
