Hey there, ffrm24!
We appreciate you reaching out on Apple Support Communities. We’d be happy to take a look at the behavior you’re experiencing with Safari and Mail.
To get started, the settings for your iCloud email address are set up automatically after logging into iCloud and enabling Mail in Settings > Tap Account > iCloud. For peace of mind, you can review those settings by entering your email address into Mail Settings Lookup at: Mail - Official Apple Support
Regarding Safari, we’d recommend following the steps included in: If Safari displays a blank page or quits on your iPhone, iPad, or iPod touch - Apple Support
For easy access, you can find those steps below as well:
If you can't load a website or webpage, or Safari quits unexpectedly, follow these steps.
Connect to a different network
Try to load a website, like www.apple.com, using cellular data. If you don't have cellular data, try connecting to a different Wi-Fi network and then try loading the website.
Restart your device
Turn off your device and turn it on again. Here's how:
iPhone
iPad
iPod touch
Clear website data
You can clear website data occasionally to improve Safari performance. If you still need help, follow these steps:
1. Go to Settings > Safari.
2. Tap Clear History and Website data.
3. Tap Clear History and Data to confirm.
If the same behavior occurs, are you able to load websites in other web browsers? Are all webpages affected? When you connected to a different network, did the same behavior occur?
Cheers!
