iOS 18 Mail Search Results Limited on iPhone 16

I am encountering the same issue on iPhone 14 Pro Max with 18.1 installed. It is really annoying as I am basically not able to find mails in my inbox anymore. All search results are almost a month old or older. Newer mails are never found.

When will there be a fix??

Apple is real quiet on this one.... HELP!!!!!!!! I'm travelling sales and can not access important info to refer back to when needed!

I have contacted Apple three different times now about this issue and they are essentially clueless. A "senior technician" has called me twice now with zero results and no commitment to any type of fix. He even said this may be "expected behavior" for the new IOS software which is a nightmare answer. Apple has totally lost their focus on the customer and if you cannot search your emails on the phone what is the point of the device!

I deleted and reloaded my email accounts into Mail and it fixed mine. They now show what I was searching for, and are in date order, although still have the 'Some results may not appear' message down the bottom.

I set up one (that rhymes with email) and the rest seemed to work. (I have multiple as well). Its still a bit sketchy (may be my iphone11 or home internet causing the reversion) but generally seems to eventually work. Still shouldn't happen. Lots of things getting 'fixed' that don't need fixing in the name of "innovation". (Or they like to call it 'optimization'). If it doesn't work or is harder to use, then its neither optimized nor innovative. Developers need to assess if it is a genuine improvement, and if not, then leave it alone.

As another user posted earlier, simply removing all the email accounts (other than my @icloud.com email) and adding them back in resolved it for me. I have 6 email accounts. Search works perfectly for all of them again.

This has been widely reported in my workplace by many users. Search has always been very buggy but iOS 18 has made it worse.

So my phone has delayed updates. It was at 18 now it’s at 18.1.1 but my two iPads are at 18.2 and now they cannot access more than one or two old emails and only recent ones when doing a search. So I opened up my yahoo app and I have no problems whatsoever so it has to be the Mail Apple app? I was wanting to know how to Reset my Mail app?

Hopefully Apple will fix Mail so that it works across platforms, like Yahoo, Gmail and Microsoft but since companies are so much set on their Brand and Branding I am not holding my breath.
