I am the owner of a file i created but i now only have view status

Hello, I am the owner of a file that i created, but for some reason i now only have view status and can’t edit the file i have bee working on for weeks.

Does anyone know how i can get my edit status back to work on my file?

Thanks

Are you working on a team (if so, which kind of plan)?
Presumably, you aren’t the team owner or admin then?
Can you work on other files?
