Apple claims to be working rapidly to resolve an issue that resulted in some iPhone alarms not setting off, allowing its sleeping users to have an unexpected lie-in.
Many people rely on their phones as alarm clocks, and some oversleepers took to social media to gripe. A Tiktokker expressed dissatisfaction at setting "like five alarms" that failed to go off.
Apple has stated that it is aware of the issue at hand, but has yet to explain what it believes is causing it or how users may avoid a late start.
It's also unknown how many people are affected or if the issue is limited to specific iPhone models. The news was first made public by the early risers on NBC's Today Show, which sparked concerns.
In the absence of an official solution, those who are losing sleep over the issue can try a few simple fixes.
One is to prevent human error; therefore, double-check the phone's alarm settings and make sure the volume is turned up.
Others pointed the finger at Apple designers, claiming that a flaw in the iPhones' "attention aware features" could be to blame.
When enabled, they allow an iPhone to detect whether a user is paying attention to their device and, if so, to automatically take action, such as lowering the volume of alerts, including alarms.
According to Apple, they are compatible with the iPhone X and later, as well as the iPad Pro 11-inch and iPad Pro 12.9-inch.
Some TikTok users speculated that if a slumbering user's face was oriented towards the screen of a bedside iPhone, depending on the phone's settings, the functionalities may be activated.
Apple said it intends to resolve the issue quickly. But, until then, its time zone-spanning consumer base may need to dust off some old gear and replace TikTok with the more traditional - but trustworthy - tick-tock of an alarm clock.
