Inbox not in sync between web client and Android e-mail

Inbox not in sync between web client and Android e-mail

I've been using Zoho Mail for about 3 months and my web client inbox has never matched the inbox of my Androd e-mail client (stock app).

What I've noticed is that if I archive an e-mail in the web client, it's often still visible in my Android inbox.

The only way to synchronize the inboxes is to remove the Zoho account in Android and then re-configure it.

Has anyone else encountered this issue?

Sync frequency set to Automatic (Push) in Android.
Days to Sync set to All in Android.
