Apple Watch compatibility

How come the most recent app update removed seeing my blood sugar at a glance on my watch face? I don’t always have the free hands to hold let alone open my phone and app to do a simple blood sugar check. Also I wish I could clear alerts for the app on my watch. Some nights when I am putting my baby back to sleep my blood sugar spikes and I don’t have my phone with me and the constant alerts keeps my baby awake. Please return the watch face feature.
Also the alarms used to wake me up. What happened? I don’t wanna die in my sleep..

The alerts do not have the correct frequency

The app is solid besides the fact that the alerts go off every 5 minutes regardless of the frequency I set. It is INCREDIBLY annoying and the app has been doing it for 4years with no change. I can tell it to beep me every 3 and a half hours, and it will still go off every 5 minutes

Sensor and or transmitter failure

For my current and last 3 sensors, it would fail on day 6 or 7. The dots would be all over the place even after calibrating. It gives false lows like saying I was 90 when I was really 150+. It once said I was 54 but I was really 150+. The only good thing is they send a free replacement each time. They should look into why the sensors and or transmitter is failing so frequently. Yes, I know they’re phasing G6 out. I was having false lows when I was on G7 (almost a year ago) but hoping they fix this when I go back.

Inconsistent and frustrating

Woke up and checked my blood sugar through the dexcom app and my app says it’s not working correctly? Says to re download the app and when I do my current cgm that I have on no longer works so I’m forced to put a new one on. Had several times where my cgm isn’t reading for 30+ minutes or even hours.
