Flagged email missing after update

Hello Kathylavin,

Thanks for reaching out in Apple Support Communities. We're happy to help.

Let’s see if we can help you locate those missing emails. Have you seen and tried the suggestions found in About missing information after you restore you iPhone, iPad, or iPod touch with iCloud backup? 

Is there another Apple device you receive emails on? If so, are the emails showing there?

Reach back out if you still need help.

Have a great day!
