iOS 18.3.2 disrupts iCloud Mail delivery for users

The recent update to iOS 18.3.2 has caused issues for some iCloud Mail users. Many people have reported on platforms like Reddit and MacRumors that their iPhones are not receiving new iCloud emails automatically. Users have stated that they need to manually refresh their Mail app to see any new messages. Despite having the correct settings, these users are not getting their emails pushed to their devices, which is supposed to happen right away with iCloud Mail. Affected users are frustrated, stating that everything worked well on the previous update, iOS 18.3.1. Push notifications are designed to alert users immediately when new emails arrive. In contrast, other accounts, like those from Microsoft, appear to be working fine. This indicates the problem might be specific to iCloud Mail. Some users have also reported issues with email delivery in the newer iOS 18.4 update. With so many complaints, it is likely that Apple is aware of the situation. Users hope that a fix will be released soon to resolve these email problems.
