(I've attempted to get an answer to this issue through your support site, but no one is answering; so maybe this is a better venue....)
When someone subscribes to our newsletter, receives the confirmation email and clicks the link therein, the h1 of that page they are taken to states they are already registered. That's confusing and inaccurate.
I've spent hours trying to sort through your docs for an explanation and unfornately it is greatly lacking.
On this page, http://support.mailpoet.com/knowledgebase/customize-your-confirmation-pages/, you state:
This page isn’t visible in your Admin and it cannot be redesigned there. Why? There is a technical reason, and the geeky crowd will understand: creating an option panel for a single custom post type would be an overkill for most of our users. We try hard to keep things simple.
Simplicity is 'nice', but not when it is put in front of functionality.
On this page, http://support.mailpoet.com/knowledgebase/confirmation-and-unsubscribe-pages-are-blank/, you state that 'Redirect ungly URLs' in Yoast must be turned off. That upsets tons of other issues; and Yoast is on literally millions of WP sites.
It's been over six months since your postings regarding this issue. Have you not come up with fixes for this yet?
We are considering your Pro version, but if this issue cannot be solved, it makes no sense to us to pay $100 and then have to code it ourselves.
Your reply is eagerly awaited.
