We have a landing page to unsubscribe (type denylist), but when our customer clicks it from a email it says "The landing page is not currently available".
The landing page is published and I do a test from the landing page and it works so I don't know the problem. We have seen that the url that the customer gets and the test is different, there are uuid in it:
Can you help us?
The "page not available" is the error page defined for the landing page, isn't it?
Are you by any chance using oragnizational units in your instance?
