Germany didn’t choose hydrogen because of its greater lifting capacity, they had to use it because the US was the only country at the time with industrial quantities of helium, and they weren’t exporting it. The Hindenburg was originally planed to use helium, but once the Zeppelin Company resigned themselves to having to use hydrogen, they added addition passenger staterooms to take advantage of the excess lift capacity.

Genshin Impact had that problem on launch. After a few months they added a setting to reverse (fix, in American terms) the OK and Cancel buttons on controllers. It was especially bad on XBox controllers on PC, as originally the green button was cancel and the red one was OK.
