Official wording
Reason: A software defect in Version 7.9 of the pump software for Tandem t:slim X2 and Tandem Mobi pumps, when used with Control IQ+ technology, will cause the pump to incorrectly interpolate glucose trends when the Estimated Glucose Value (EGV) is above 255 mg/dL at the start or end of a gap in data collection due to a lapse in connection from a paired continuous glucose monitor (CGM) sensor, which can lead to under-delivery or over-delivery of insulin based on inaccurate result leading to severe cases of hypoglycemia or hyperglycemia.
