Yahoo Not Updating Email on iPhone Mail App

I have an iPhone 15 on iOS 18.2.1. For the last month or so, my Yahoo email in the Apple Mail app isn't updating regularly. I try to push the email and update, but many times I won't get new emails even though there are multiple emails available on the Yahoo app on my same iPhone. If I delete my Yahoo email account in the Mail settings and then re-enter my log-in information, it always updates my incoming emails right away. Is anyone else having this issue and what can be done to fix it?
