Messenger links and the App Store

Messenger inherits Facebook's browser, which is the strictest one we measure.

Shared lineage

Messenger uses the same Meta WebView as Facebook, so store links fail the same way: Apple's redirect into itms-appss:// cannot be handed off, and the page stops loading.

Detection is by the Facebook family markers, with Messenger identifying itself specifically:

/FBAN\/MessengerForiOS|FBAV|FBAN/i.test(navigator.userAgent)

Why chat traffic matters

A link shared in a conversation carries a recommendation with it. The person tapping it was told by someone they know to install this app, which is the highest-intent traffic there is.

Losing that tap to a blank page is worse than losing an ad click, because it also makes the person who shared it look like they sent something broken.

Business messaging

If you run support or sales through Messenger, any store link in a template or an automated reply has the same problem. Those templates get sent thousands of times and are rarely tested from inside the app.

The fix

Same as everywhere: a routing address rather than a store URL. Given Messenger's strictness, expect the manual fallback button to appear more often here than on Instagram, and make sure its wording is clear.
