Difference between Hi 10 X & Hi 10 XR

I’ve got an Hi10XR, it works with Microsoft Pen Protocol styluses rather than the H3 HiPen, like current Hi10X, which I’ve just bought for keyboard and H6 stylus. I’m assuming that there’s no difference between X and XR, there’s no reference to XR anywhere now. Can anyone confirm or know anything more?

What i saw till now the difference are:
1.Processor 4100 vs 4120
2.Hi pen 3 vs Hi pen 6( Microsoft pen compatibility)

That’s it

Thanks, that’s what I thought. Current Hi10 X has the same specs, perhaps Chuwi thought it was worth differentiating and just abandoned that. I’ll be annoyed if the Hi10X I’ve just bought (with H6 and N4120) gets here and the keyboard doesn’t fit the XR…

Even more confusing: Before Chuwi released the XR, they also made a batch of 10X’s that used the H6-pen digitizer. The difference was only noticeable in the serial number, so you effectively didn’t know which Hi10X you would be getting when you ordered. So the only difference I know was the processor (4120 vs. 4100) but now even that difference seems to be gone. Chuwi and their mysterious practices I guess…
