Remedy
1. I remove both buds from case. Charge case to full batt.
2. Once buds are like 50% batt, i throw 1 side into case to charge. Once tat bud is full, i remove and put the other one in.
3. Once other is charge, i throw both in case to charge.
4. I uninstall wearables app and reinstall.
Finally, it works.
