I’ve charged several times so far without issue, but this morning the charger snapped into place but didn’t register it was charging. Different USB-C port didn’t help. I tried disconnecting/reconnecting from the watch and wall several times also didn’t help. Wiggling the connector on the watch side a few times worked then stopped charging. Eventually I got it to a sweet spot where it charged. I didn’t see anyone else report this issue, so maybe my watch or charger has an issue?
