I just acquired a Kindle Paperwhite 7th gen (KP) reader to replace an old Kindle Keyboard (KKB) which died. I also have Kindle apps on my iPhone XR and iPad. With the old KKB, I never had a problem syncing to last page read no matter which device I had most recently used. Last page read syncing worked flawlessly across all three devices. Now, with the new KP, I am unable to sync from the KP, which was most recently used, to either the iPhone or the iPad. Both of those devices tell me I'm already on the last page read, but that is not the case. It is the most recent page on those Apple devices, as I just loaded the book to those devices. However, I am into Chap 4 on the new KP and I can't get either Apple device to sync to that page.
