The same thing happens to me. If I am logged in and click on the link in the email, it takes me to the thread and I can interact with it normally.
If I am not already logged in, I click on the link in the email and it takes me to the linked thread (or freebie page, or whatever the email link is for). Then I click Login/Register at the top right corner of my screen and log in. The forum redirects me to the home page and I have to go back to the email and re-click the link to get to where I want to be. It would be nice if upon logging in it took me back to the page where I was when I clicked the login/register link instead of the home page. Since the forum updates where username and password are on separate pages while logging in, the forums no longer play nice with BitWarden password manager either. It always would auto-fill the login info, but now I have to do it manually.
