Whoever is in charge of the Switch technical help at Tencent is going to need some more training. A customer who purchased a Switch in China has noticed that their Joy-Con is already experiencing drift. When they reached out to Tencent for help with the situation, the rep they talked to had an interesting response.
The customer noted that they experienced the Joy-Con drift when playing an imported copy of The Legend of Zelda: Breath of the Wild. Tencent's rep suggested that the customer give the Joy-Con a try with a game that wasn't imported to see if the problem was still there.
Obviously we all know that imported games have no impact at all on Joy-Con performance, and thankfully the customer experiencing this issue knew that as well. Let's hope they can get a better answer and more help from Tencent moving forward.
