I also had no more records after the update – after a downgrade it counts again. I do not use Wordfence or similar, but the console did not show me any error messages. :-/
Sorry, I don’t have a GitHub account.
Can you leave your thoughts on this one, specifically on whether you really want a visible setting or whether visiting the last viewed period is good enough?
Save the last setting would be an option, too. But I would prefer an selectbox, like “View X, View Y, Last View” or so on…
