Hi! I see you want to set YouMail as the default app for calls on your iPhone 17 Pro Max. Let's get that sorted for you.

On iOS 18.x, Apple introduced a setting to change default apps for calls. Here's how you can set YouMail as your default calling app:

1. Open the Settings app on your iPhone.
2. Scroll down and tap Apps.
3. Tap Default Apps at the top of the screen.
4. Choose Calling from the options.
5. You should see a list of compatible apps, including YouMail. Tap YouMail to set it as your default calling app.

If YouMail is not appearing in the list, please ensure the app is updated to the latest version from the App Store and that you have granted any necessary permissions to YouMail for call handling.

Try these steps and let me know if you can set YouMail as default now or if YouMail isn’t showing in the options. I’m happy to help from there!

Are you satisfied with the solution I provided?

YouMail isn't showing in the options. I have verified that the app is up to date.

Thanks for letting me know that YouMail isn’t appearing in the default calling app options even after updating. Since the app is up to date and still not showing, let’s try a few deeper troubleshooting steps specific to iPhone and YouMail integration:

1. Reinstall YouMail
Sometimes cached data or outdated carrier info inside the app can cause issues. Uninstall YouMail, restart your iPhone, then reinstall YouMail from the App Store. This often resets the necessary permissions and integrations.

2. Check Call Blocking & Identification Settings
Go to Settings > Phone > Call Blocking & Identification and make sure YouMail is enabled. This is essential for YouMail to function fully and can affect its ability to appear in default call options.

3. Reset Network Settings
Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. This won't delete your data but will reset cellular, Wi-Fi, and VPN settings, refreshing carrier configurations that YouMail relies on.

4. Verify Permissions
Go to Settings > YouMail and confirm all permissions (Microphone, Contacts, Notifications) are granted. Missing permissions can limit the app’s functionality within iOS.

5. Check for iOS Updates
Although you’re on iOS 18.7, check for any smaller updates in Settings > General > Software Update in case a patch fixes app integration issues.

If none of these help, it could be a compatibility hiccup or a temporary bug between YouMail and iOS 18.x. In that case, contacting YouMail support directly at [email protected] for deeper investigation might be best.
