Vivoactive 4 recently got updated to V8.30 and GPS SW 6.0.

Post this SW updates, optical sensor stopped working. Green LED lights are not on anymore.

Also, watched stopped tracking steps and it stopped steps reminder as well.

I have the same issue. Reset the watch. Still no joy. No response from Garmin support. Very frustrating.
