IOS 15 notifications don't work

Hey there, mlaforet,

Thanks for visiting the Apple Support Communities. It sounds like you are not receiving notifications for emails and messages as expected. We are happy to help!

First, make sure your notifications settings are correct for the apps, and that the "mute notifications" option is not set for either app: Use notifications on your iPhone, iPad, and iPod touch - Apple Support.

Then, ensure you do not have a Focus set that would interfere with the delivery of those notifications: Use Focus on your iPhone, iPad, or iPod touch - Apple Support

If you still need help after that, don't hesitate to respond back with more details on what is happening. For example, you say they are not working all the time. Do you find that they do not work at certain times of day, or in certain locations? The more details you can provide, the better.

Best!

Thank you for following up, mlaforet,

Depending on the situation, it may be expected at times for your phone not to provide a notification. For example, if you use an Apple Watch, you will receive notifications on either the watch or the phone, but not both. Additionally, if you have the Messages app open in a thread with a specific contact, you will not receive notifications when that person messages you.

That said, if you're not receiving notifications in other circumstances you typically would expect to, we do want to continue investigating this with you. It sounds like you've done a lot of troubleshooting already, so we recommend getting in touch with Apple Support directly next. You can do that here: Get Support.

Enjoy your weekend!
