Adding Mail Accounts:

A. Setting Up an iCloud eMail?:

If you are having issues setting up iCloud eMail, go here: Create a Primary eMail Address for iCloud Mail - Apple Support

B. Use a New App Password:

Do you use an App Password? If so, try a new App Password. Sometimes, changes (i.e. updates) are made to the device, and then mail server syncing becomes an issue (which is what a new App Password it intended to fix). Go here for gmail: Sign in with App Passwords - Google Account Help - Goog

Reset the Home Screen Layout:

If apps and widgets are not showing up as they should, then you need to reset the Home Screen Layout...

Go Here: Move and Organize Apps on iPhone - Apple Support

You'd have to add back all the widgets that you can recall being back on there. So, write down what is currently on the Home Screen.

Scroll to: Reset the Home Screen and Apps to their Original Layout

1. Go to: Settings
2. Tap: General
3. Tap: Reset
4. Tap: Reset Home Screen Layout
5. Then... Add the apps back

Drag it from the App Library to your Home Screen:
