iPad and iPhone Mail not synching

Hey there hkbs,

Let's team up to get Mail in sync with both devices. To start, we'd like to rule out some general details, along with gathering more details to better understand what's happening:

1. You mentioned that when organizing email messages in your iPad, it doesn't reflect those changes on your iPhone. What occurs when you make changes in Mail on your iPhone first?
2. When did this first start?
3. Is this only occurring with one of the email accounts set up in your devices, or are some working without any issues?
4. Sometimes unexpected behavior can be resolved with a restart: Restart your iPhone and Restart your iPad
5. We see you have a compatible iPhone model, so the latest for it would be iOS 16.1.2. If you're using a compatible iPad model, the latest version is iPadOS 16.1.1. In each device, you can verify this within Settings > General > About. In case you needed it, this link shows how to first back up, then Update your iPhone or iPad.

Cheers!
