We've discovered that the subscription cancellations don't work. If the user clicka, it does not give any error, but then in the backend is not deleted from the subscription.
Can you help us?
In the Acymailing configuration page, tab "Interfaces", did you select a menu in the option "Menu linked to AcyMailing"?
If so, make sure this menu is public otherwise non-logged-in users won't be able to access the AcyMailing URLs.
It´s difficult to explain writing you. Here you have a video to undestand well the problem: https://www.loom.com/share/b5f22c1fee004eaf8523f7bb21b136a0
Please use the contact form (https://www.acymailing.com/contact/) to raise a support ticket for this and include login credentials for your backend and a link tot this thread, so we can have a look at it.
I have just seen this answer... the client did not inform us about them until now, which makes it even more urgent. I'm sending you the access data right now through the form. THANK YOU
