I have had my Air3 for about 3 weeks. The batt charging hub stopped charging batteries. I have tried multiple chargers that all worked a week ago. It can transfer charges from batts but doesn't actually charge when plugged in.

Hello, there. May we double confirm that the charger can charge the battery when you put the batteries in the aircraft but does not charge the batteries when you use it with the charging hub, right? If so, please send the charging hub back for diagnosis and repair. Here is the link: https://www.dji.com/support/repair?from=store_homepage
