When you say the voyager is buggy when you try and turn pages what is the issue? I have a problem with the (stupid, hateful) haptic buttons. The ones on the right mostly both go backwards, periodically it works as expected. I thought this was a hardware fault, but maybe you are experiencing the same issue?
As a for instance, if "the quick brown fox" is the last words on my current page, and I turn to the next page, I'd expect the first words to be "jumps over the lazy dog" but in this instance "jumps over the lazy dog" is typically somewhere mid page.
I've also had issues, again when syncing my position from a different device, where the location totally bugs out if I try to swipe back to the previous page. This happens infrequently, so I'm uncertain if there's any logic at play, but the location is often way off of where it should be when aiming for the previous page.
