Thanks folks I fixed it for him.. Turns out it needed a hard reset AND was due a software update , I dont think they fact he just bought about 20 books for his trip also helped.Also I put it on airplane mode for him ..this might also assist our bandwidth issues.This! Forcing a restart seems to sort most Kindle niggles out. Mine had a wobble not so long ago where it wasn’t charging properly (plugged in for ages but the battery level not going up) and a restart sorted that.
A thank you from him would have been nice btw
