I don’t see the Texthelp PDF Reader when I open PDFs from Google Drive Shared drives

If you have a PDF that is in your Google Drive Shared drives folder, you may notice PDFs do not open with the Texthelp PDF Reader nor is there an option to open with Read&Write for Google Chrome.

This is because the PDF Reader can only access PDFs that are in your personal My Drive folder in Google Drive. 

If you can make a copy or move the PDF you want to open with the PDF Reader to your My Drive folder in Google Drive, you can then open it with the Texthelp PDF Reader.
