FYI some of you may be prompted to grade some older books. Due to investigation of @bibliothecary 's bug - Grading not available depending on how book is marked 'finished' - #7 by brandon - I found some user books in a bad grading state, which I’ve now resolved. You should have never been prompted to grade these books before.
Only impacts <50 users though, so not too many!
In addition, I’ve spent some time improving the tv episode quick ‘+’ progress button, so you’ll see some improvements there
