The iPhone 6 and 6 Plus were released in 2014 and discontinued nearly two years later in most markets. The phones ceased getting software updates in 2019 with the launch of iOS 13.
Although Twitter dropped support for iOS 12 in early 2021, iPhone 6 users were still able to use an older version of the app. The Twitter app was updated this week and it now does not support iOS 13 either. The latest version of the app requires at least iOS 14.
iPhone 6 and 6 Plus users are saying that while they can still view some tweets on the timeline, most other features don't work anymore and the app is barely useable.
Only a few people will be affected though, as only 2 percent of iPhone users are on iOS 13 or older version of Apple's smartphone operating system. So, if you have the iPhone 6, 6 Plus, or an older iPhone, you can only use Twitter through the Safari browser.
