Why does my link show a blank page in Instagram?

Apple redirects apps.apple.com to the itms-appss:// scheme, which in-app browsers cannot follow or hand to another app. Full mechanism in the main write-up.

Why does it work when I paste it into Safari?

Safari can hand the scheme to the App Store. The failure exists only inside in-app browsers, which is why testing by typing the URL never reproduces it.

Does a short link fix it?

No. It resolves in the same browser and meets the same redirect. More detail.

Do OneLink, Branch or Adjust fix it?

No. They measure the tap accurately and the tap still lands nowhere. More detail.

Is Android affected?

Rarely. Android has intent:// with a fallback, so taps survive. More detail.

What is the shortest valid store link?

https://apps.apple.com/app/id123456789. Country code and app name are optional. Full format reference.

How do I add campaign tracking?

ct and pt on the App Store URL, referrer on Google Play. More detail.

Do UTM parameters work on App Store links?

No, Apple ignores them entirely. More detail.

Why does my link open the store when the app is installed?

The universal link could not be verified, so iOS fell back to the listing. Checklist here.

How do I detect an in-app browser?

Markers in the user agent, with fallback signals since iOS 26. Code and table.

Which ad objectives are affected?

Traffic, engagement and conversions. App install objectives open the store natively. More detail.

Do QR codes have this problem?

No, the camera hands the URL to the real browser. More detail.

How do I test properly?

Post the link to a story visible only to you and tap it from inside the app on a real phone. Full procedure.

How much is this costing me?

Spend times the in-app iOS share times the failure rate. Worked example.
