In case anyone else has an FMP account linked to an email address they don't use often - I just found an email sent on 30th August informing me that, from September, my previously viewed records will only be available with a valid subscription. They will, apparently, update with the exact date nearer the time.
You may, of course, all be far more efficient than I am and download viewed records immediately, but, when I am "hot on the trail", I have been known to postpone the downloading while I continue searching
. I have already found several I had forgotten to download, plus some I had not thought relevant at time of viewing (primarily because I had mistakenly prematurely killed someone off!).
Going through them all is a slow process and I have vowed not to make the same mistake again
