external GNSS Garmin Forerunner 230 is connected but not finding 1 satellite

Hello.

I downloaded the Locus Map application 4.29.0 (I subscribed to SILVER), then I downloaded and bought "Garmin for Locus Map".

Locus Map sees my watch, but not my watch's GPS signal.

If I go to the satellite signal on the map and turn on the external GNSS (Forerunner 230) it doesn't find a single satellite...nothing, so navigation doesn't work either.

The phone's GPS is not the real one, so I wanted to see it with my watch's GPS in Locus Map, but nothing.

I managed to select a point on the map so that the watch could guide me there, but when I turn off the phone's GPS, the watch doesn't detect progress.

What can I do to solve this?
