Purchase
Why am I being told to re-purchase movies I bought years ago on iTunes?
Question marked as
Where are you seeing that ? If they are the same versions that you bought and if you haven't moved countries since buying them, do they not show for redownloading for free : Redownload apps, music, movies, TV shows, and books from the App Store, iTunes Store, and Apple Books - Apple Support
Or have you hidden them from there : Hide and unhide music, movies, TV shows, audiobooks, and books - Apple Support ?
Obviously if what you bought have been removed you will be charged to buy what is now in the store (and similarly if you've moved countries and want to buy them in your new country)
