EDGE 830 FAILED TO PAIR AFTER SLEEP MODE

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.
