So I updated the M96. Changing the language did not get me any further. Manually downloading did, however.
Now, I am not sure what to say.
Now the reader is... useless. When pdf quality was acceptable before, it is not any longer. I cannot read the text.

And this is NOT in the A2 mode but the "quality" mode.
See the image attached from the same document as earlier.
The scribble now works better. It still lags, but this may be due to the e-ink. The stylo is precise in that you can actually make out a specific point and hit it spot on. However, a decent writing speed will get you into trouble as the M96 is too slow to pick up every swing of the pen precisely.
So, this has not been helpful.
I have to say I am fairly disappointed.
PS: Booxtor, how do I get a hold of you? I have been e-mailing you through the contact form, the support form and your shop e-mail address for clearly over a week and I have not gotten a single response. Would you mind getting back to me? Thanks!
