This has been an ongoing issue, last noted in the community October 2016
On my iPhone only, if I use a flag of any color, other than red, it changes to red after 10 seconds.
I have checked iPhone & iMac Pro settings. Nothing noted to impede action.
iPhone 12 Pro, iOS 14
Hi campchocolate,
Thanks for the information. Do you have an iCloud account that you can test with? Not all email accounts support multiple flag colors.
If the issue doesn't occur with an iCloud account, you'll want to reach out to your email providers to see if the feature is supported.
Should the issue occur with an iCloud account on both your Mac and iPhone, contact Apple Support directly to further assist: Contact Apple for support and service
Best!
Hi campchocolate,
Thanks for reaching out to Apple Support Communities. It sounds like you're having an issue with changes to an email flag staying the color you've selected. We're happy to help.
Do you notice this issue occurs when changing the flag color in a specific account, or any?
You also mentioned this only occurs on your iPhone. If the flag color is changed from your Mac or another device does it show as expected on your iPhone? If so, is this again for a specific account, or any?
We ask as the ability to change the flags color may be limited by your email provider. However, we recommend ensuring the steps are attempted to help isolate the issue.
If needed, check out the section "Flag your email" in the article here: Use mailboxes to organize email on your iPhone, iPad, or iPod touch

Cheers!
Thank you for your response. Yahoo! and gmail accounts are linked to the general email app. I notice it occurs with email received from either account.
If I flag an email yellow (or any color) on my mac it shows up red on my phone. If I flag an email on my phone yellow (or any color), after about a minute it automatically changes to red.
Flags in mail on iPhone revert to red
