I’ve noticed something strange on my iTunes account recently - missing tv shows I absolutely remember buying at one point, but nowhere to be seen now. One I remember is “Adventure Time”. Just now searched my email and found receipts from iTunes Store for “Adventure Time Vol 1” dated 22 Nov 2013. I see receipts for the other seasons of the show too, they were not rentals as far as I’m aware. Then sometime in last few years the content disappeared from my account and devices. In fact I just opened up iTunes Store now, found the Adventure Time series still available on iTunes, but it’s asking to pay and saying I don’t have. This is exactly same AppleID I used 10 years ago to buy this content ugh.
