Data loss issue Again!

New to CD 2020 for Mac. Twice now, while working on a very detailed drawing, I've been redirected to the Corel login page for no apparent reason.  Once I cancel the  login, not only is my drawing is closed, but all saved versions created over the the last 3 days are gone. Both times I lost 3 days of data. Yesterday, I continually saved the file as I worked on it.  After redirection, the only file found on my Mac was saved 3 days ago. This is the file Corel sees as the "Open Recent" file. I have been getting a message related to the "Corel default file location", anyone know what that location is?  None of the files have been saved to the Corel cloud.Logically, I can't understand how this is even possible.
