I guess it’s not unexpected per se, but the peak hours are solidly Chinese daytime work hours with an extended lunch break, and hitting a bit of Europe’s morning. But no American peak hours, unless you count after-work hobby coding (6-9 pm Pacific?) which tells you indirectly a bit that American adoption is not a major driver of revenue for them. Or that the after-work ‘hobbyist’ is the main audience, which is also plausible.
