I have this problem in Australia. After you pressed redeem, it shows" You must enter a valid code" but that code is provided by iTunes. What other code I can use to enter?
To everyone
[doublepost=1512617555][/doublepost]This is soo frustrating; I opened the Apple Store app and scrolled down and found the Plotagraph+ redeem section again. Finally!, on first sight. But.... no. Seems like I get the widely known error try again message. I went to the App Store app and saw that there was an update available for the Apple Store app so I updated. As soon as it updated I opened the app and scrolled down to the redeem section and touched the blue bar again. Now I got another error: "Unfortunately, due to the high demand, this offer is no longer available. Keep an eye on the Apple Store app for new offers."

I send an email again and will keep y'all updated on this.
Thanks so much for this post! I read that the offer ends January 15, 2018, but I don’t see Plotagraph under Discover in the Apple Store app. Do you know if Apple ended the offer early or is Plotagraph just not showing up on my end for some reason?
