I’m seeing a problem for websites who use a staging area to make changes to their website, then push-to-live the upgrades. This overwrites the newsletter subscribers in the database, with an older list of subscribers. Pushing a new website to live essentially erases all the new subscribers every time a revised website is pushed live.
If Newsletter kept its own database this wouldn’t happen; but with subscribers kept in/under wp_options, how can we push a new website live while preserving new subscribers?
