Glider (OGN) or CN (OGN) Not Found
My Glider (OGN) says Not Found
The data fields Glider (OGN) and CN (OGN) are looked up from the OGN device database https://ddb.glidernet.org/
The values are looked up from the ICAO ID. If there is no match (the device is not registered) then it says Not Found or Not Set.
To fix this, add that ICAO ID to the OGN Device Database. Then wait a few hours for it to propogate.
