I also am having this issue. The link was sent to me today by the company account owner, but I receive the "Wrong Link" message, even in an incognito browser - I've tried Chrome & Firefox.
I called support but they just said to have the company account owner delete it and try again.
I do have multiple "accounts" tied to the same email address, but I do not believe this should be the issue -- it simply does not bring up anything but the same "Wrong Link" message.
Edit:
I was unable to get this working on my computer, but I tried clicking this link from my phone's email client (Outlook) and it opened the link in a browser successfully. Maybe this will help someone else out there with the same issue.
Unfortunately, after logging in with an existing user (same email address as the invite was sent to), I get a "There's an issue on our end. We're on it" message and asks I try again. Whatever account/email I try to login with does not work. Something in the process is hiccup-ing.
