iOS 16.6: Native Mail App: Email Messages Activate inside of apps can't be dismissed - user stranded!

 iOS 16.6

Mail app for iOS 

Date: 08/22/2023

Description:

Today I came across an especially bad bug with the native iOS Mail app. I've gotten it to reproduce with multiple iPhones running 16.6.

I'm not sure how to describes but the problem is something like this: if an app activates the iPhone's native iOS Mail app, the user gets complete stuck when trying to cancel out of writing the email. The user is stuck staring at an unresponsive email message and has to force quit the app. 

This is much easier to show than to describe, so please take a look at a video of the bug:

Here’s a video of the bug. I can get this to happen 100% of the time. An extraordinarily debilitating bug with the native iOS Mail app

Steps to Reproduce:

1. Install the Native iOS Mail app and have it be the default 

2. From inside an app like Facebook, select an option to "Send Email"

3. From a generated email message select "Cancel"

4. Select "Delete Draft"

5. Select "Cancel" (nothing happens)

Result: Users are unable to dismiss ("cancel out of") email messages created by the native iOS app when these messages are shown in app 

Example: Using iOS app, select an FB page with "send email" button - from generated email message, select "cancel" 

Expected: User should always be able to exit out of an email message - an app like the Facebook iOS app should not rendered unusable by exiting out of a message 

Head to a Facebook page that has a "Send Email" option. 

Select the "Cancel" option from this email.

Select "Delete Draft"

User is completely stuck. A force quit is required to get the Facebook app working again.
