Hi,
Thank you – that (hopefully) resolves the issue!
Note, that I came to Edit Preferences not through my Profile, but through the link in the "update emails" itself.
The link in the emails (see screeshot) reads: You are receiving this email from Apple Support Communities. You can change your email preferences in your Apple Support Communities Profile.
And the link leads to the "Edit Preferences" page (the "Manage Email Notifications" page is not visible / linked from "Edit Preferences")
According to common "unsubscribe" practices in emails, I would expect that an "unsubscribe"-type of link leads me to a page where I can unsubscribe from the type of email I just received (and not unsusbcribe from 'additional potential future' emails or whatever you would call it in that case).
Hence, this "unsubscribe" link in the email should either go to the Profile page, or the Manage Email Notifications (where I can actualy unsusbcribe), NOT to Edit Preferences.
Hope, someone from Apple reads the above...
( Personally, I think the idea to split between past and future threads is a bad design in the first place )
Daniel
