Super C app for iOS: Share Sheet - Facebook Messenger UI not displaying correctly

iOS 13.4.1
Super C app for iOS (version 2.0.4)

Description:

Here's yet another one of my obsessive compulsive ramblings example of a problem that numerous apps have with the iOS share sheet and the Facebook Messenger UI.

There's an app out of the beautiful Quebec region of Canada called "Super C." This app is a coupon app.

This app has the function of creating custom lists, which can then be shared using the iOS share sheet.

However, the same old problem appears with this app....

Take a look at these screenshots:

This is with the iOS set to dark mode. As you can see, the Facebook Messenger UI is not displaying properly.

This is with the iOS set to light mode. The Facebook Messenger UI is not displaying properly, here, either.

Steps to Reproduce:

1. Download the Super C app for iOS and create an account
2. Add items to your grocery list
3. Select "List" from the bottom UI
4. Select the share option
5. From the share sheet, select Facebook Messenger

Result: The Facebook Messenger UI is not display properly in the share sheet by the Super C app - there is a discolored bar at the top

Expected: The Facebook Messenger UI should always be displayed correctly
