Some iPhone users are seeing red when it comes to an unintentional new side effect of the new iOS 13 software.

NBC News reported that a large number of faithful iOS users are finding certain emails (as well as their ability to reply to said emails) disappear from their mail clients entirely.

But as frustrating as this sounds, it wasn't caused by a bug , or even some sort of iPhone malfunction. It was all related to iOS 13, the software that powers iPhones, and its latest features that had just been rolled out.

The newest version of the default iPhone email app just received a sleek new update in late September, which brought a slew of changes to the app. If users haven't changed it out for a new program, such as Google's official Gmail app, or a mail client from another developer of their choice, they've likely been stuck with the same odd new design decisions from Apple.

"I end up deleting the email by accident instead of replying to it," Shannon Watts, founder of gun control association Moms Demand Action told NBC News. "If I’m lucky, I’ll remember who I was replying to and then search for their name in trash. But it’s incredibly frustrating and time consuming."

The trash icon has simply been moved to where the reply icon used to be, and the fact that they're too close together is a pain point for many users. Social media has been ablaze with users frustrated by the fact that they've inadvertently deleted important messages when all they wanted to do was reply to them. Apple has not offered an official response to these jilted users.

While there isn't currently an option within the app to change the placement of the reply button and trash buttons, there is an easy fix beyond switching the email app used by default. According to Mobile Nations senior analyst Rene Ritchie, one simple solution is just turning on the "ask before deleting" feature on the iPhone.

To do this, simply head to Settings > Mail. Then scroll down in the Mail Settings menu to find "Ask Before Deleting." It's under the "Messages" header. You should see the option with a toggle switch next to it. Tap it to turn the feature on. In the future, your iPhone should prompt you with a menu to reply in the affirmative before it goes about automatically deleting your emails.

It may not be perfect, but at least it's a viable solution for now.
