Updated 02/04/2022: Dexcom's reply below is not really helpful. Especially when the sensors/transmitters cost ~$3K every few months. The phone is the latest model and runs Android 12 with all security features in place. Clearly, this is a QC problem on your end and lack of devops support is extremely appalling considering that this is a medical application. Hope there is some way to report this to the licensing authorities. You cannot release a medical device with such poor app support and no other way to see our readings. We need better support especially when you're charging so much money and forcing us to shell out even more for just changing 2 dollar batteries on your sensors. Switched to a new phone and the dexcom app no longer works. With no prior warning! Stuck with dexcom transmitter and sensors without a way to monitor levels now. This is unacceptable for a critical medical app. Please fix it or let users use it along with "the warning" that it is incompatible and may not work as expected. Thats what you did for g5.
