Watch will not completely charge
I have an Apple Watch 6. I had issues with update to latest OS, had to unpair my watch and phone, finally updated. Since then, my watch is not charging. I have rebooted it several times. I am using the original charger, and had no issues before updating. Finally got it to charge to 90%, left it on charger overnight and this morning was at 75%.
Do I need to send it in for repair?
