I have no idea.
To this point, over the past year, I've gradually increased views with my subscriptions, as one would expect. I update weekly, every Wednesday night. I have every week for more than a year.
I mean in July, the last week, I was getting 12-15K views on each page released.
As of August, every release I have put out, (August 2, 9, 16) have averaged 6-8K views per page.
I changed nothing, did nothing different. It is completely inexplicable and they are not responding to my emails (yet).
