"You're currently subscribed to YouTube TV through Apple in-app purchases, so we're writing to let you know that, starting March 13th, 2020, YouTube TV will no longer accept payment through Apple in-app purchases," reads the company's email. "You'll be billed for one final month of service and then your in-app purchase subscription will be canceled automatically on your billing date after March 13th, 2020."

The email doesn't explain why Google is removing one of the ways people can pay for YouTube TV, but the likely reason is that the company doesn't want to give Apple a cut of its subscription revenue. Depending on how long someone has been a subscriber, Apple takes either a 15 or 30 percent cut of every in-app subscription.

The practice has been a contentious one for a long time. However, Google isn't the first company to stop accepting App Store subscriptions. In 2018, Netflix stopped taking in-app subscriptions through both the App Store and Google Play Store. Practically speaking, you'll still be able to use the YouTube TV app on your Apple devices, you'll just need to subscribe directly through the company's website.
