Date: 03/13/2019

Description:

A "403 forbidden" message appears in the preview image when you go to share a Zappos product. This happens when you use the Facebook Messenger option and attempt to share a product from the iOS app, via FB Messenger.

Please see the attached screenshots.

Steps to Reproduce:
1. Download and launch the Zappos iOS app (version 5.1.0)
2. Go to any product in the app
3. Select the sharing option in the upper right hand corner of the screen
4. Select Facebook Messenger
5. Note that the preview message displays as "403 Forbidden"

Result: When sharing a product from the Zappos iOS app, the preview image generated by Facebook Messenger displays as "403 Forbidden"

Expected: Users should never see a "403 Forbidden" error message from a legitimate link shared via Facebook Messenger

If you send a user a Zappos product via Facebook Messenger, this is what the link will look like when they open Facebook Messenger. 403 Forbidden makes users nervous about opening the link...

Select the share option in the upper right hand corner of the screen, from any product featured on the app..

The preview image in Facebook Messenger is a "403 Forbidden" error message. Please fix!
