Not here for a discussion, just a simple suggestion.
Stop the subscription pop-up barrage on your website.
It might be surprising to discover that many subscribers are working, have deadlines,
and don't have the desire or patience to click away your constant pop-ups about subscription updates.
As many have already stated here, I don't spend good money for your service to be innodated with upgrade ads.
(And it's not a notification setup solution -- please don't even try to suggest that.)
Laterz,
(or maybe goodbye -- time will tell.)
