You have a policy of making people sign in once a week. Like many others I view the site through a desktop at home and work, a laptop, an ipad (app) and phone (android app) and sometimes more than one browser on the PCs.
So most of the time I arrive at your site on any device I'm not signed in.
I don't understand why even on an app you'd sign someone out, and of course you get to present me with ads when I'm not a subscriber.
So I might just go that way. Because the result is that there's not much point in paying a subscription. (Plus is ok, but not why I pay.) I pay it to support you as I did AtlasF1 originally. But if you force me to view the content as if i'm not subscribed, I'll stop subscribing - the view isn't much different.
