Why my previous pdf are deleting automatically

Hi @Aradhya29276846pvvb,

Hope you are doing well. Sorry for your experience with Acrobat Reader Mobile.

We would like to have some more information to dig into the issue:

1. Have you checked the different accounts you might have used with Reader Mobile (Sign in with Adobe versus social sign-in)?
2. Which platform do you experience the issue with? Reader Mobile Android, Reader Mobile iOS, or Acrobat online. Please login to Acrobat online (link https://acrobat.adobe.com/)  using the same login credentials as in the app and confirm whether your files are visible in Acrobat online under the Documents.
3. Are all the files missing, or only some files?
4. When did the issue start? Any details about any actions taken then?
5. Reader Mobile app build version, device model, and OS version.

Look forward to hearing from you.
