Also experiencing charging issues with S7 41mm cellular. Tried many chargers and cables and outlets along with new “fast charging” puck. Took to Genius dude at Apple Store, and he could not diagnose. He recommended I contact support for replacement. Received replacement four days ago, and last night replacement did the same no charging routine. I notice when this happens watch will not awaken after a jiggle into nightstand mode. Also when this happens, sometimes the password screen activates while puck is attached. I gotta think we have a software or firmware issue. Very frustrating, I’ve had 4 Apple watches, Series 4-7, this is the first to not behave well. Boo
