Thanks for contacting us! I can understand that it must be frustrating to have your documents missing after just signing up for an account. I haven't heard of this issue from any other users recently, but I think I may know what is happening. Is it possible that you have multiple email addresses that you use? Sometimes when a user reports a missing document, it can be located on a Lucidchart account associated with a second email that you frequently use and accidentally made an account for. If you can fill out this form, we can help you more in depth about this particular case to see if there are multiple accounts or even another cause for the issue.
