So I'm guessing we're no closer to knowing the actual facts about this "issue", are we? They removed the dock from the store (but still available in some territories, like Canada)
Is the scratch thing a very widely reported issue, or a case of loud minority who are, without putting too finer point on it, being too careless with the system.
I hate to be the "it's not happening to me, so it's not true" guy, but having spoke to around a dozen people I know who have Switches, none of them have reported seeing scratches due to docking and un-docking their system. I personally dock and undock my system multiple times a day (a good 3-5 times at least) and have yet to see any kind of damage.
I'm not saying it's not happening, it obviously is, but I just wonder why. Maybe some docks are manufactured more narrowly than others? I guess I'm not going to start worrying until I hear official word from Nintendo.
For people talking about cables - I'm using a "Cable Matters" branded USB-A to USB-C charge cable going into a KMASHI 15,000 mAh power bank. I only used it once yesterday, but it charged fine. Didn't feel hot or anything.
