Exway doesn't care about USB-C conformity
While I'm glad that they took the time to hold support's feet to the fire over this, doing that sort of thing is almost certainly a waste of time.Seldom will you find a support team who can understand a technical hardware problem like this, and even more seldom will you find a company that responds to this with anything other than "nothing we can do, sorry". You're not going to get the "Wow, that is our bad, we'll retool our entire production line to account for that issue that nobody else complains about and send you one as soon as it's ready, thank you" that you so desire.
