Reset furthest page read on Sideloaded books?
I've read you can reset 'furthest read page' online through the 'manage your Kindle' site, but none of my sideloaded books appear there.
I tried deleting and reinstalling those books on both my devices, but that doesn't work as it seems the data for pages read lies in amazon's servers.
Is there anything I can do? I still have the original epubs on my pc. Could I possibly convert them again and fiddle with the settings in such a way to make kindle recognize it as a new book?
