I believe this has also happened to our account. My personal work account, a full admin access account, has vanished with no trace as of how/why. I conducted an audit of our user activity log and am not finding a "removed user" log. I also never received an email notification about any change to my account or access. Although I have access through our accountant file, and am able to resend an invite, I am mind boggled as to how this would just randomly happen to accounts. By the looks of this thread, it has happened quite a bit in the past months with no real answer from QB. This is absolutely unacceptable! Unsure of re-adding myself so I can prove I went missing in the first place. Has anyone received a solid explanation? Next steps? Was it ever resolved?
