White screen when accessing X (Twitter) "Subscribe" page via Arcsphere browser.
Environment:
- App: Arcsphere
- Feature: Integrated In-App Browser / Webview
- Device Date: February 7, 2026
- Comparison Browser: Google Chrome (Working as intended)
Description: The Arcsphere internal browser fails to render the "Subscribe" page on X.com. While the main feed and profile pages appear to load, clicking "Subscribe" or navigating to a subscription-gated URL results in a persistent white screen. The same URL functions correctly when opened in external browsers like Google Chrome.
Steps to Reproduce:
- Open Arcsphere and navigate to an X.com profile or post.
- Click on the "Subscribe" button in the top right corner of the X interface.
- Observe the screen transition.
- Compare by opening the same link in Google Chrome.
Expected Result: The browser should load the subscription tier details, pricing, and "Subscribe" call-to-action buttons.
Actual Result: The page remains entirely white/blank indefinitely. No error message (like 404 or 500) is displayed; the content simply fails to render.
Technical Observations:
- The issue may be related to User-Agent restrictions or missing support for specific JavaScript elements required by X's subscription modal.
- The video shows the X app/web interface loading initially, but failing specifically on the "Subscribe" redirect.
