@joanna It’s only the cellular items (ones with a SIM-card capability) that are affected. And that’s because those have GPS receivers in them. It’s to fix an issue affecting global GPS. The problem is known as the Week Number Rollover issue, and its caused by GPS systems recording the passage of weeks as a 10-bit figure. This means that when they hit week 1,024 (just under 20 years) their count resets. As a consequence, some older hardware is thrown off course — both figuratively and literally. It’s similar to the Millennium/Y2K bug, which was also caused by the reset of a date count.
