Zocdoc app for iOS: Share sheet - auto-generated subject line disappears the second time the email dialog is activated

 iOS 14.0.1

Zocdoc app for iOS (version 4.61)

Date: 10/04/20

Description:

Here's a minor bug that I have only seen once with another iOS app.

Like almost all apps, Zocdoc has an option to "Share" the app via a menu option. This "Share" option activates the iOS share sheet. If the user selects the email option from the share sheet, they will see the following text in the email message and in the subject line:

You'll notice that the when you first open up the email message, the subject line is auto-generated.

However, if you open the email option a second time...

The subject line is deleted! I've tried this with a great many apps, and I have only noticed this problem happen one other time. 

Steps to Reproduce:

1. Download and launch the Zocdoc app for iOS

2. Select the "Sign up/Log in" option 

3. From the "My account" screen, select the "Share Zocdoc" option 

4. From the iOS share sheet, select the email icon

5. Select "Cancel"

6. Select "Delete Draft"

7. From the iOS share sheet, select the email icon again

8. Note that the Subject Line is now blank

Result: The auto-generated subject line (which displays as "Check out Zocdoc") disappears the second time the user activates the email invite via the iOS share sheet

Expected: The auto-generate subject line should not disappear if the user activates the email invite more than once
