Apple Mail randomly does a screen refresh (Iphone 16 pro + iOS 18+)

Apple Mail randomly does a screen refresh and all emails are reloaded. And sometimes this reload does not work (emails are empty) and I am forced to exit the app and restart it.

Does anyone have a fix to solve this problem?

And then:

It only started happening with this particular iPhone, others (like an iphon14pro max) does not have this issue.

Thanks.
