My old keyboard kindle screen froze & I now have a lovely refurbished Paperwhite. All my books were on the Cloud & I have transferred the ones I haven't read, onto the Device in their collections.
However, I don't know how to remove the ones I've now read and get them back onto the Cloud. If I tap on them i can just see 'book complet' 100% - Can't seem to find the 'Remove from Device' icon.
