Once it kicks in, those with iPhones and iPads using much older iOS software will no longer be able to access Sky Go.

For those not aware, the popular GO app offers instant access to live and on-demand TV along with being able to set recordings remotely and check out what's on now and next.

It even lets you download shows and movies which can then be watched when away from a mobile or Wi-Fi connection.

Sky Go is massively popular but you'll need to be running iOS 13, iOS 14, iOS 15, iOS 16 or iOS 17 to carry on using it.

"For Sky Go on iOS, we’re removing support for iOS 12 by 17 September. We’ve updated the app and sky.com pages to reflect the change," Sky confirmed.

"To ensure we provide the best possible experience to Sky Go customers, from time to time, we stop supporting older operating system versions. Users who are on this iOS version won’t be able to use the Sky Go app after this date. They’ll need to update to iOS 13+ to continue using the app. This impacts iOS users only, not other Sky Go platforms."

If you have an iPhone or iPad you can check if your system software is up to date by heading to Settings > General > Software Update.

Sadly, some much older devices - such as the iPhone 5s and iPhone 6 - can't switch to iOS 13 as they are no longer compatible with the latest operating system.

This latest update comes as Sky has also confirmed that it will cancel the subscriptions of some of its customers in October as the TV firm continues to restrict channel access for those still using some of its oldest Standard Definition (SD) TV equipment.

“If you don't contact us or upgrade, your Sky TV will be cancelled and you'll lose access to these services on your payment due date in October,” Sky said on a help page on its website.

The firm is now urging those with old set-top boxes to apply for a free upgrade.
