Email not marked as read in iOS 13.3

Hello mrwrighty,

I see that you're having an issue with mail not showing as read on your iPhone. I understand wanting to get this resolved, and I'd be happy to look into this with you.

Let's begin by having you remove the account from your iPhone and then add it back and test to see if the issue persists. The second article will guide you through those steps, if you're using the Mail app. Look at the section titled "Remove your email account and set it up again".

If you can’t send or receive emails on your iPhone, iPad, or iPod touch

If the issue remains, reply back to the following questions.

1. Which version of iOS 13 are you currently using?
2. Are you using the Mail app or a third-party app?
3. Do you have more than one mail account on your iPhone? If so, do you have the same issue with those accounts?

Thank you for using Apple Support Communities.

Hello mrwrighty,

Thanks for those additional details. Where you able to remove the account from your iPhone and then add it back and test to see if the issue persists?

Are you able to check your mail from a web browser? If so, does this mark the email as read on the iOS device?

We look forward to hearing back from you.

Hello mrwrighty,

We look forward to hearing back from you on if removing the account and adding it back helped.

Cheers!
