Can't Open Cloud Files in Acrobat Reader Free Version Android phone

Can't open Cloud PDF files. There's no access to the cloud Files anymore on the free version Adobe Acrobat Version

18.2.0 182935. No access to all the Cloud files. It says log in and I can't log in when I try on this Free Version. All the Cloud access and PDF files and other files on local are all gone from one day to the next day. What happened and how do I get the files back? If I get another Adobe Acrobat Free Reader which one do I get at the APP Store? How can I Update the Version I already have? Is it broken forever? Any help would be appreciated. Thank you folks.
