Since updating to the latest firmware (2018-11-30_15-14_2.0_babe727) page turning on Kindle has stopped working.
To be more accurate, touching either side of a page does not make the screen refresh with a new page. However, if I then touch the centre of the screen to bring up the page carousel it opens on the new page!
Something clearly got broken in the last update - shouldn’t be difficult to fix.
I am on the latest Play Store version of Kindle (18.104.22.168) & it worked perfectly until the Boox firmware update.
