Not possible to unsubscribe

[francis]

When clicking on the unsubscribe link in the notification mail 

I get following page 

This error can occur if the original link to unsubscribe has been altered. Please try the original link again.

Is obviously not the case ...

@francis has this been resolved now that we've improved our email subscription features? I wanted to double check.

I have reported this issue.

What type of email are you trying to unsubscribe from? Is this still happening if you try to unsubscribe?

These are the standard notification mails which contain an unsubscribe link.  Check screenshot in the description

Tried it multiple times
