Feedback on issues with missing file versions

After logging in again, I found that most of the files (in the first half of last year and this year) were lost, and the remaining files can only be viewed but not edited.
If possible, could you help me solve this problem? Thank you very much!


Hey @mochifulu - are these all files that you own? Or were they files owned by someone else that were shared with you?

If they aren’t owned by you, I’m wondering if the real file owners have changed the permissions of the file so you can no longer edit them.
