MEDTRONIC has warned of an issue which may affect people using the Guardian Connect continuous glucose monitoring (CGM) system.
A potential connectivity issue requires everyone using the platform to upgrade to version 3.2.2 of the Guardian Connect app as soon as possible.
The company said the identified issue relates to Apple iOS versions 11.3 and 11.4, which can sometimes prevent people from receiving a ‘Lost Communication’ alert when the app is closed by the iPhone’s operating system in certain situations.
The iOS may close the app without alerting the user that it is no longer running or communicating with the Guardian Connect Transmitter – meaning alerts that could be associated with hypoglycaemic or hyperglycaemic events would not be received.
Medtronic has also advised that users periodically check that the app is still running, and be especially mindful when running several applications at once.
