I have tried setting up Gmail as IMAP and played with different settings for about a week now and still have the same issue. I have contacted both Google and Samsung about this to no real answer or help. For now I'm giving up as I have spent way too much time on attempting to get this resolved. Using Outlook instead as it has zero issues with notifications. Thanks again for everyone's help and time. If I figure this out or hear anything more I'll keep this updated.
