My health app used to record my routes but over the last 2 days it has stopped and just shows a period of time I exercised for. I use my gear s3 watch to record the ride which transfers to the app on my galaxy s8. This usually then links to strava, but this has now stopped too. Phone and watch seem to be up to date, with location settings on. I've changed no settings so I don't know why this has started. Very frustrating!
