Change in ownership and edit mode

Hi,

I worked on 2 new draft files few days ago. I open Figma again and initially i did see all my files as it was, suddenly it goes missing from the recent files. I was able to retrieve access of one through the prototype preview, but it shows that I can only View and not edit. It seems my file ownership is removed and i can only view my own file. Has anyone else gone through this? Please explain what is happening.

Did you log out/log in/change account?

Yes, I did. It still remained in View mode. I had to copy paste the frames to another draft file to edit it.
