My Watch4 used to work perfectly with Strava app but, for about a year now, the Strava app won't find a GPS signal. I can run Strava on my phone just fine, and routes work well, but there is no heart rate data coming from the Watch4. Any idea how to fix this? I've deleted the app and reinstalled it numerous times to no avail. Strava tech support originally said that there would be an update to fix this, then they stopped responding.
Many thanks
