I've found that having VPN and setting it to any other country other than UK, I can get the 150credits. But, it can take up to 90 minutes and brings up the "Sorry, there are no videos available" box 20-30 times.
This is time taken away from playing the actual game, which in my mind is ludicrous!!
Gamers shouldn't have to jump through hoops to gain a few credits when others seem to get them in 20/30 minutes and even quicker by using multiple devices.
Please, please sort out this anomaly and make it the same for everyone....PLEASE!
