Dexcom G7 Shows Major Differences From Finger-Stick Readings

I have been using Dexcom G7 sensors for a long time. Since government coverage became available, all of the sensors we have purchased have started malfunctioning consistently about four days before the end of their intended use period. The sensor frequently displays warnings that it is unable to obtain a reading, and even when it does provide a reading, there are significant differences compared with my finger-stick blood glucose measurements. As shown in the image I provided, there are very large discrepancies between the glucose meter and the Dexcom app when the measurements are taken at the same time.

We never experienced this issue with the sensors we used before government coverage began. At that time, the readings were quite consistent. Now, we are encountering the same problem with almost every sensor, which makes diabetes management much more difficult and creates a serious health risk. In addition, despite paying approximately $318 for a three-month supply, we are unable to use the sensors effectively until the end of their intended lifespan.

I request that the reason these sensors are failing prematurely be investigated, that defective sensors be replaced with new ones when necessary, and that I receive a clear explanation regarding the measurement discrepancies. I want this issue resolved as quickly as possible so that I can manage my diabetes safely and with confidence.
