iOS 18 iCloud mail does not sync with other devices; all other mail accounts work fine

Yesterday I did upgrade my main devices: iPhone to iOS 18, iPad Pro to iPadOS18 and Mac to Sequoia. Everything worked fine, but I have an issue with my iCloud email account: all actions sync between iPad and Mac, but iPhone is not syncing properly. All other configured email accounts sync fine.

I already tried to logout from iCloud, restart my device and log back in my iPhone and it did not work.

Next best thing could be to perform a reset, but I would like to save time... Has anyone experienced this issue as well?

OS:

iOS18.0
iPadOS 18.0
Sequoia 15.0

iPhone 15 Pro Max, iOS 18

Latest update: I did sign out, restarted my iPhone, had to login back again (which implies to download your entire information from iCloud - photos, notes, emails, messages, etc, which took a considerable time), and after a couple of hours the issue seemed to be resolved. It was a uncomfortable solution, involving friction and time… even had to reactivate my cards on Wallet…

This is the issue I am having. I have no idea how to fix it either. I even had an  rep on the phone trying to get help but they didn't know what the issue was!! Pretty crappy stuff!
