I‘ve an AW3 which I use since day one. During the last few days I‘ve had several issues with charging the AW. As soon as I connect my AW with the charging puck it beginns to charge but sometimes it stops charging after a few minutes. Once I‘ve seen an error „Charging accessoire not compatibel“ (or similiar, my AW is setup German). I‘ve two charging places for my AW and the error occured on both, despite I use original Apple charging accessoire on both locations. I‘ve already rebooted the AW and cleaned everything but the error occurs still sometimes. Any guesses what the problem can be?
