It worked because there was a PC inside. Today's Smart TVs are very limited when you try to replace what a PC does.
Even the idea of putting the attachment into your dropbox or gdrive fails on all the Smart TVs I've seen.
I'm going with there isn't a fully functional TV for this use.
Does anyone know of a manufacturer/model that would allow attachments to be opened that were sent as a part of an email. I recently discovered that my fairly new Samsung Smart TV does allow me to access email, but does not allow any attachments within the email to be opened.
Thank you to all.
