Sync Issues for iOS Mail

Hi Team,

Recently my iOS Mail has stopped syncing imap changes to my inbox.

Example: Email arrives in my inbox and syncs on all devices. I read the email and archive it on my laptop. This sync does not replicate on my iPhone (email remains in the inbox).

In this example, if I read the email on my iPhone and archive the same occurs in that email remains on my laptop.

This has only started to occur recently - have I inadvertently changed an imap setting on my account (buildyourdynasty.com.au)
