I integrated my Zoho and Gmail email accounts via POP3, so that I could view gmail emails in Zoho.

Everything worked fine, and I had Zoho import all of my old messages from Gmail. It did great, importing everything from 2016 until May.

But that's where it stopped—it has not imported any messages that arrived since May. Unfortunately those recent emails are the most important ones. New messages that have come in are showing up, and I still have plenty of storage left.

Why aren't my recent emails importing? Help? Thanks!
