Hi all. My wife and I just leased a 2021 etron. We had been charging it at home without a problem on our 240v. We went on a weekend trip and charged it on a 120v. Now, it won't charge on our home 240v. The green light is indicating that it is charging but nothing is happening. I "reset" the cable by holding down the 50%/100% button and it still doesn't work. We took it to Audi and they installed a system update/charged it on their system but it still doesn't charge at home. Any advice would be greatly appreciated.
