Dexcom G6: "Temporary Sensor Issue" / "Calibration Error 1"

[loopy321]

I started a sensor, got two readings and calibrated. Now I see "temporary sensor issue" on the Bluetooth screen.
Waited 45 minutes, now I see "Calibration Error 1"...
Not sure what this is or if there is something I need to do?

I see in the code that this is the message reported for a transmitter responding with 0x12 and 0x08, but it is weird because the sensor was otherwise stable before restart.

Any ideas?
Thanks!

I see the error in the logs , but not clear what happened.

Anyhow, I waited another 30 min and recalibrated, and started getting readings again. Weird...
