I have a Reach RS2+ and I cannot find the static/dynamic setting mentioned on this page in the app: Settings overview | Reach RS2/RS2+
I have a working NTRIP correction input and can get FIX status. I also have the device configured to broadcast its own correction output over LoRA.
That page only shows me the elevation mask angle, SNR mask, GNSS systems, and GNSS update rate. I do not see anything about position mode.
I have firmware 31.8, app version 10.2, and am connected from an iPhone to the Reach over WiFi.
