Sensors not working on watch series 3
So after updating the watch software to version 8.7.1, watch has stopped recording any data from heart rate sensor, activity tracking, wrist wake.
Tried hard reset, erasing all content, works for briefly 1 time then again same story. Contacted apple authorised service centre- cannot fix it. Think somekind of software problem, any way to downgrade as this is the last official version I suppose
