We recently discovered a software issue in the Accu-Chek Connect app versions 2.0.0, 2.0.1, and 2.1.0 that can result in incorrect bolus recommendations. This software bug may result in errors in the active insulin calculation, creating the potential for a false high insulin bolus recommendation. An insulin bolus delivered based on potentially incorrect bolus advice could lead to serious health consequences such as hypoglycemia.  Diabetic Investor 4-12-2017
