Saving file problem on Document Cloud with a PDF

Hello,

I frequently use your document cloud pdf service.

One of my file is now corrupted after having saved it on the cloud.

It's now impossible to open it.

I highlighted and commented quite a lot on that document.

Can I recover an old version of my file on the cloud ?

The problem occured on an Androïd version of Acrobat Reader.

Thx for help.

Best regards

David Leroy
