After this instruction, you need to turn off and then turn on the watch. The solution did not work for me without turning it off / on (long press light button and then press start/stop button)
I did that (because I also resetted the watch to start from default and than did the sync process) but it didn't fix the problem. Before the latest FW update it wasn't a problem for me...
I had this exact problem and I read on other forums it was to do with the watch not knowing the trajectories of the satellites and the file named "CPE" on your watch needing the be up to date with the latest trajectories. You can find if this is up to date by navigating to the "About" section on your watch or viewing it on a computer via windows explorer or mac equivalent when the watch is connected. I was constantly syncing my watch with the Connect app on my phone and the problem persisted so that does not automatically update it.
I read on another thread that you should connect the watch to the computer (doesn't need to be via Garmin Express) and delete the folder "RemoteSW". I did that and went for a run and it didn't find any GPS during the 30min run.
I had never used Garmin Express on the computer so downloaded that, signed in and synced my watch. Went into the RemoteSW folderon my watch when it was connected to the computer and the file labelled "CPE" was updated with that sync.
Went outside to start a run and it worked straight away.
