Hardcoded PRIMARY_DOMAIN Usage Across Multiple Screens** + +**Problem**: Multiple screens were using hardcoded `AppConstants.PRIMARY_DOMAIN` instead of the current user domain, breaking domain switching functionality. + +**Root Cause**: Several screens had hardcoded Referer headers that didn't update when users changed domains. + +**Solution**: **CRITICAL DISCOVERY** - All screens must use dynamic domain loading for headers: +```dart +// CRITICAL: DO NOT CHANGE THIS METHOD!
