push mail iPhone/iPad OS18.3.2 - works unreliably and sometimes not at all

Apple Support blatantly denied this issue existed on Friday (14th), and advised me to use another email client like Outlook if I weren't satisfied with the “rate of push” – and that “it takes as long as it takes for emails to arrive” – even though I said it is likely a iOS18.3.2 issue. Rolling back to iOS18.3.1 resolved the issue completely.

I did notice that after the update the Customization Notifications for Primary Inbox Alerts were reset back to "Off" (this must be the new "default"). Try going to Settings/Apps/Mail/Notifications/Customize Notifications/Primary Inbox and toggle Alerts to On and select your desired Sound.

I had the same problem with my iPhone 13 Pro Max on 18.3.2 until I updated my iOS to 18.4. On 18.4 push notifications for Mail work perfectly again.

I've read the discussions about the same issue and tried delete Apple mail and reinstalling it, finally my iPhone 16 pro and my wife's iPhone 16e (both are iOS 18.4.1) got back the push notifications and the sound again.

I am happy to say that after applying iOS18.5, all my mail issues have been resolved. Notifications, with sound, are working as expected.

After applying the update, I did go into my mail app notification settings and changed my sounds to a new sound, then back to my desired sound in both the Alerts and Customized Notifications settings. I then did a soft reset (volume up, volume down, press the side button until the Apple logo appears) in case that was needed to re-initiate my desired preferences. Those steps may not be required.

Same problem. I disabled Push for my mail account and switched to Fetch at 15 minute intervals. That’s working for me. I’d be interested to know if that works for others who want to try it.

Settings > Apps > Mail > Mail Accounts > Fetch New Data

Unfortunately Apple already stop signing 18.3.1 – usually you can downgrade within a 7-8 day window after a software release. At this point the only option would be to wait for the next iOS release, and hopefully the issue is fixed. A possible workaround would be to set iCloud Mail from "Push" to "Fetch", with perhaps a 15 or 30 minute interval.

18.3.1 is still signed by Apple so it can be downloaded from https://ipsw.me/ and restored via Finder.

Same issue - have to set mail app to fetch mail now (was on automatic) to receive emails unless the app is open, the icloud servers are not pushing emails out (thats my opinion anyway) only seems to of happened since March update - surley the amount of icloud mail users apple realise there is an issue ?????????????? frustrating as I have gone to the trouble of changing all my info over to iCloud mail from Outlook.com, which was never an issue with receiving mail

Yup, push works again for me on 18.4!

I’m experiencing the same problem on both the iPhone (16 pro max) and iPad Pro (M1). When I updated to 18.3.2, push email through iCloud was broken. I only use iCloud email. Now, I have to open the Mail app to prompt download of new messages. I had not experienced any issues prior to the update.

Same here. I spoke with Apple Support and told them I suspect it was a bug in iOS 18.3.2 because of all the reports on the Internet. I also sent an email to Apple Product Feedback. Hopefully they’ll provide a fix before April’s iOS 18.4 update. Next time, I’ll wait for my iPhone to decide when it’s time to update.

After applying the 18.4 update, new mail is now in my Inbox, but I don't receive a mail notification or sound on a locked screen (evening though this setting is enabled) nor when the Mail app is open does it play a sound when I receive a new mail banner notification.

I've noticed an extra message when I open the Mail app since applying the 18.3 update: "Connecting...." Either this "Connecting" process is ignoring the sound notification features (all are enabled with an Apple provided sound) or some other bug has been introduced. I've seen this reported by users in Reddit as well. I'm hoping for a 18.4.1 or 18.5 update to resolve this critical function.
