So lately, my Macbook Pro 15" late 2014 has some bugs in the Mail app. It takes hours to receive a mail from anyone. Whereas my phone receives the mail in seconds after it being sent, the Mac takes hours to do so. The recent mail does not show up at all! The only e-mails I can see are from 5 or 6 hours ago. I don't believe the network is an issue since the phone and my laptop are on the same Wi-fi.
Any help is appreciated! Thanks.
