Hello, my name is ***** ***** I will do my best to assist you. Give me a few minutes to look over your question and I will respond shortly.
The Gmail app is marking your e-mail as read and the POP3 protocol does not download them. Google is asking users to switch to IMAP on their user's computer to resolve this issue. Can you tell if you are using POP or IMAP on your desktop e-mail program?
Just checking in to see if you need anymore assistance. Let me know.
