Hey @Ft.Yadu, Can you please provide more details on this issue? When did you create the file that is now missing? Are you able to see the file if you log in via browser on the webapp? How many files are missing? Are they of a specific type (post, webpage, or video)? Have you tried signing out and then back in on the device to see if that help?
Let us know about your observations, we are here to help!
