Facebook Messenger not working

[Malhar99]

When users access Facebook Messenger in incognito mode on iPhones without having the Messenger app installed, there is no clear error message indicating the absence of the app. This can lead to confusion and a suboptimal user experience.

Steps to Reproduce:

Open an incognito tab in Safari on an iPhone.
Navigate to Facebook and log in.
Attempt to access Facebook Messenger.
Expected Behavior:
An error message should be displayed, clearly indicating that the Messenger app is not installed and providing guidance on how to proceed.

Actual Behavior:
No error message is shown, leaving users unaware of the missing app.

Additional Information:

This issue is specific to iPhones in incognito mode.
Users might assume a functional problem with Messenger or the website, causing unnecessary confusion.
It is unclear whether this behavior is intentional or a bug.
Proposed Solution:
Implement an error message in incognito mode on iPhones for users without the Messenger app. The message should inform users about the missing app and provide a link to download it from the App Store.

Attachments:
If applicable, include screenshots or video recordings demonstrating the issue.

Environment:

iOS version: [e.g., iOS 17.0]
Safari version
This detailed description will help the developers understand the issue better and work towards a resolution.
