Adobe Scan files missing; suspicious email change in permissions

Hello, I had many legal and confidential files scanned in Adobe Scan which were being uploaded to Document Cloud.

Today, when I accessed the Adobe Scan, none of my past files were there.

Also there was an email from Adobe stated below:

Hi Ritu ,

Your administrator has altered some permission settings for Adobe Express for K-12.

This does not affect your access to other Adobe products and services.

If you think this was done in error, please contact your administrator.

Regards,

The Adobe Team

I don't have an administrator, then how can my files deleted or missing from document cloud or adobe scan??
