I too have the same issue. I purchased a new tablet, just a week ago - so I am confident that the caches are pretty empty (although I have tried clearing the caches anyway).
My tablet is a Samsung Galaxy Tab S2 9.7, running Android 7.
I have several email accounts, one of them is a gmail account (not my primary gmail account). This secondary gmail account receives Quora emails, always without any body text. The header is always fine. My W10 laptop displays the emails correctly, as does my old Android tablet (running Android 4). I have forwarded the faulty Quora emails to my old tablet and they display correctly there.
I have checked the settings (Incoming, Security, Port, Imap path, Outgoing server and port, etc.) - they are all identical to my other Gmail account, which I have no issues with.
