## Request for Action
As this issue is believed to originate from the X app's WebView, we request investigation and fixes for App Store link behavior within WebView on iOS 16/17 environments.
## Additional Information
- Confirmed to work properly on iOS 18 and later
- Confirmed that opening the same URL in Safari and tapping the "Open Instagram" button successfully navigates to the App Store
## Investigation Results
We have confirmed the same issue occurring with multiple apps besides Instagram, and we have determined that this is highly likely to be a bug in the X app's WebView.
- Actual behavior:
- After tapping the "Open Instagram" button, the URL changes from `instagram.com` → `apple.com` → `instagram.com`
- The visual display remains on the Instagram screen throughout, and the App Store does not launch
## Behavior Details
- Expected behavior: App Store app launches and displays the Instagram download page
## Conditions for Occurrence
- Using iOS 16 or iOS 17 device
- Instagram app is not installed
- Opening an Instagram-related web page within X app's WebView
- Tapping the "Open Instagram" button under the above conditions
→ Does not navigate to App Store and shows no response
# Issue Report
## Problem Overview
On iOS 16 and iOS 17 devices, when attempting to navigate to the App Store from within the X (Twitter) app's WebView when the target app is not installed, the transition to the App Store does not occur.
