I purchased my Edge 830 in DEC 2019 and it has worked perfectly for months without the slightest glitch. Last week (MAR 2020) I noticed my power, cadence, and HR were not paired after I put the device in sleep mode. All attempts to pair the devices on the fly were unsuccessful; the computer just spun and nothing happened. I stopped the route, but that made no difference. I had to shut the computer down and reboot, losing the data continuity from the ride. Garmin, please bring back nirvana.
