The Lora configuration page gives the range as 902 to 928 instead of 868 to 928. I went out side with one of the receivers and an orange box appeared in the upper right of the screen that said something about detecting a location change. I went to the Lora configuration screen and 868 was the low end again.
The second unit has been power cycled multiple times and has had a good clean fix for many minutes but the range is still 902 to 928.
