  • Tap Calendar.
  • Tap Accounts.
  • Select your email account.
  • Toggle Calendars off, wait a few seconds, and then toggle it back on.

• Re-Add Email Accounts

If the problem persists, try removing and re-adding your email accounts:

On both iPhones:

• • Go to Settings.
  • Tap Mail.
  • Tap Accounts.
  • Select the email account and tap Delete Account.
  • Restart the iPhone.
  • Re-add the email account under Settings > Mail > Accounts.

If none of the above steps resolve the issue, it might be necessary to contact Apple Support for further assistance.
